OBJECTIVE:To study the adsorbability of plastic transfusion bottle and infusion set to diazepam. METHODS:With the reference of plastic-bottled 5% glucose injection,HPLC was used to determine the changes of mass concentration of diazepam adding into plastic-bottled 5% glucose injection at different time;disposable plastic infusion set was connected to simulate intrave-nous infusion and determine the changes of mass concentration of diazepam in the liquid effluent at different time. RESULTS:The mass concentration of diazepam in glass infusion bottles group was higher than in plastic transfusion bottles group. The adsorbabili-ties of solutions showed the strongest at the time of 15-20 min. The mass concentration of the effluent liquid from the glass bottle group was about 80% of the original concentration and plastic bottle group was about 67%. As the time went on,the adsorbability was gradually saturated at 60 min and the concentration rose again;the mass concentration of the effluent liquid from the glass bot-tle group returned to 95%of the original concentration at 80 min and the plastic bottle group was about 75%of the original concen-tration. CONCLUSIONS:Both plastic infusion bottle and infusion set have strong adsorbability to diazepam. It is suggested that the dosage of diazepam should be increased by 25% to 33% while plastic-bottled 5% glucose injection is used as solvent for intrave-nous drip.

Objective To explore the clinical features and diagnosis of primary immunodeifciency disease caused byTyk2 gene mutations.Methods Clinical data from the ifrst case in China diagnosed of primary immunodeifciency disease caused by Tyk2 gene mutation were retrospectively analyzed, and related literature was reviewed.Results One year and 3 month old boy suffered with repeated pulmonary infection, chronic otitis media, intractable eczema like rash, repeated skin abscess, HSV infection, intracellular bacterial infection, and remarkedly increased total IgE. It was detected that compound heterozygous mutations of c.2269C>G in No. 16 exon and c.149delC in No. 3 exon inTyk2 gene. Literature searching found other 8 cases (5 males and 3 females) of immune deifciency patients caused byTyk2 gene defects, all of which hadTyk2 gene homozygous mutations and presented with repeated infection of paranasal sinus and lung. In the 8 cases 6 cases were combined with mycobacterium tuverculosis infection, 4 cases had repeated virus infection, 4 cases had meningonecephalitis, 3 cases had intractable eczema like rash, 2 cases had salmonella enteritis, 1 case had remarkedly increased total IgE, one case had elevated eosinophils, 5 cases were born in intermarriage family and 1 case died of meningitis caused by unknown etiology.Conclusions When patients have repeated paranasal sinus infection and lung infection, combined with intracellular bacterial infection (including mycobacterium tuberculosis infection), and repeated virus infection or intractable eczema like rash, with or without increased total IgE, immunodeifciency disease caused by Tyk2 gene defection should be considered. Gene sequence analysis can assist in early diagnosis.

ObjectiveTo observe protective effects of agmatine (AGM) on inflammatory response and spleen immune function in mice with trauma.Methods Forty-eight adult male C57BL/6 mice were randomly divided into three groups (n= 16 each), including control group, model group (bilateral femoral fracture and removal of 35% of the total blood volume), and AGM group (trauma/hemorrhage & AGM 200 mg/kg). Eight mice in each group were sacrificed at 3 hours and 24 hours, respectively, after modeling, and blood samples and tissue homogenate of spleen and liver were collected. The contents of tumor necrosis factor-α (TNF-α), interleukins (IL-6, IL-1β) in serum and liver tissue were determined with enzyme linked immunosorbent assay (ELISA). Serum aspartate transaminase (AST), alanine aminotransferase (ALT) and lactic dehydrogenase (LDH) were determined with automatic biochemistry analyzer. Spleen proliferation response stimulated with concanavalin A (ConA) was evaluated with methyl thiazolyl tetrazolium colourimetry (MTT).γ-interferon (IFN-γ) and IL-2 releases were determined with ELISA.Results Compared with control group, 3 hours after trauma/hemorrhage, the levels of serum TNF-α, IL-6, and IL-1β in model group were significantly elevated [TNF-α (ng/L): 145.38±31.50 vs. 23.06±11.14, IL-6 (ng/L): 496.94±50.76 vs. 47.13±17.47, IL-1β (ng/L): 321.31±43.02 vs. 29.25±16.24,allP< 0.01]. It was found that AGM treatment could alleviate the increase in serum pro-inflammatory mediators induced by trauma/hemorrhage, such as TNF-α (ng/L:111.56±25.47 vs. 145.38±31.50), IL-6 (ng/L: 412.56±44.33 vs. 496.94±50.76), IL-1β (ng/L: 273.38±45.25 vs. 321.31±43.02,P< 0.05 orP< 0.01). Twenty-four hours after trauma/hemorrhage, serum pro-inflammatory mediators were recovered to the levels in control group. There was no significant difference in TNF-α and IL-6 levels at 3 hours after trauma/hemorrhage among groups. Compared with control group, the expressions of liver TNF-α and IL-6 in model group were increased at 24 hours following trauma [TNF-α (ng/mg): 32.93±4.90 vs. 26.58±2.33, IL-6 (ng/mg): 11.20±1.66 vs. 8.38±0.89,bothP< 0.01]. However, AGM inhibited the level of TNF-α (ng/mg:28.92±3.16 vs. 32.93±4.90) and IL-6 (ng/mg: 9.03±1.28 vs. 11.20±1.66) in the liver as induced by trauma/hemorrhage (P< 0.05 andP< 0.01). At 24 hours after modeling, model group and AGM group had distinctly higher serum AST, ALT, LDH levels than those of control group [AST (U/L): 405.9±31.2, 245.7±22.1 vs. 128.2±15.9; ALT (U/L): 92.1±6.3, 51.6±5.0 vs. 30.1±3.2; LDH (U/L): 606.7±36.3, 478.7±25.3 vs. 384.0±16.6, allP< 0.01]. Nevertheless,the increase in serum AST, ALT and LDH was alleviated in AGM group (allP< 0.01). Meantime, trauma/hemorrhage produced a noticeable depression of proliferation of splenic cells and IFN-γ and IL-2 release stimulated with ConA compared with control group [proliferation rate: (40.97±4.13)% vs. (89.99±7.76)%, IFN-γ(ng/L): 91.6±12.3 vs. 353.2±21.5,IL-2 (ng/L): 53.4±6.4 vs. 91.0±12.2,allP< 0.01]. In contrast, AGM notably restored the capacity of proliferation response of splenic cells [proliferation rate: (74.86±5.75)% vs. (40.97±4.13)%, P< 0.01],enhanced the release of IFN-γ and IL-2 stimulated with ConA [IFN-γ (ng/L): 327.8±23.6 vs. 91.6±12.3, IL-2 (ng/L): 74.8±10.4 vs. 53.4±6.4, bothP< 0.01].Conclusion AGM can dramatically alleviate spleen immunosuppression, excessive inflammation and organ damage induced by trauma/hemorrhage.

Objective To investigate the state of endemic fluorosis, running status of water improvement project to reduce fluoride in Jiangsu province, and to provide a scientific basis for prevention and control of endemic fluorosis. Methods In 2008, in the ten key counties of endemic fluorosis (zone), in Xuzhou,Lianyungang and Suqian, a stratified sampling method was employed to select 40 diseased villages according to their past water fluoride survey data. All children aged 8 to 12 were examined dental fluorosis, and all adults over 16 years were examined clinical skeletal fluorosis. Thirty per cent of the 40 diseased villages were selected, and 20 adults over the age of 16 in each selected village were examined by X-ray, respectively;50% of the 40 diseased villages were selected, and 30 any time urine samples of children aged 8 to 12 in each diseased village were tested urine fluoride. In each city, select a county, the status of water improvement project to reduce fluoride, water supply capacity and coverage in the county were investigated. Results A total of 3560 children aged 8 to 12 were examined, the detection rate of dental fluorosis was 38.51% (1371/3560), tooth defect rate was 5.34% (190/3560), and dental fluorosis index was 0.8. Seven hundred and eight urine samples were tested, the median urinary fluoride was 1.47 mg/L and the range was 0.08 ~ 10.08 mg/L. Clinical detection of skeletal fluorosis was 21.3% among adults over the age of 16, and X-ray detection rate of skeletal fluorosis was 39.2% (123/314).Investigated a total of 248 facilities of centralized water improvement projects, no funds to run or damaged 49, the water fluoride > 1.0 mg/L was 18. Conclusions Endemic fluorosis in Northern Jiangsu province has not been controlled completely, but has a rising trend, we should further strengthen the supervision of water fluoride reduction.
