OBJECTIVE: To evaluate the utilization and its trend of narcotic analgetics in this hospital.METHODS: The use of narcotic analgetics during the period 2005-2007 in our hospital was analyzed retrospectively.RESULTS: The consumption quantity of narcotic analgetics in our hospital increased year-on-year,much as in the consumption of morphine preparations,with oral morphine preparations dominating the 3 first places over the 3 years,however,the increase of pethidine was slowed down in consumption quantity.CONCLUSION: The use of narcotic analgetics in our hospital is rational on the whole,but measures should be taken to tighten the control on the use of narcotic analgetics.

Abstract: Objective　To observe the expression of peripheral blood stimulating molecules CD80 and CD86 in children with severe hand, foot, and mouth disease (HFMD), and to analyze the relationship between them and the therapeutic effects of children. Methods　The clinical data of 252 children with severe HFMD treated in Wuhan Hospital of Traditional Chinese Medicine from March 2017 to March 2021 were collected retrospectively. All children were treated with standardized treatment and the therapeutic effects was evaluated. The baseline data and laboratory test results of children were recorded, and the positive rates of CD80 and CD86 cells in peripheral blood were detected by flow cytometry. Logistic regression was used to analyze the relationship between the above indexes and the therapeutic effects of children. The receiver operating curve (ROC) was drawn to evaluate the value of the above indicators in predicting the therapeutic effects of children. Results　After standardized treatment, 48 children were ineffective, and 204 children were effective; the levels of serum CD80 [(2.28±0.84)% vs (2.12±0.33 )%] and CD86 [(3.35±0.96)% vs (2.23±0.41)%] in children were significantly lower than those at admission (t=2.851, 16.991; P<0.05). The levels of blood lactic acid, serum C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9), CD80 and CD86 at admission in the ineffective group were significantly higher than those of the effective group (P<0.05). Logistic regression analysis showed that the overexpression of serum CRP (OR=10.929), MMP-9 (OR=1.926), CD80 (OR=3.943) and CD86 (OR=1.947) at admission might be the risk factors of ineffective (all P<0.05). The results of the goodness of fit test for the model showed that, the goodness of fit was high (χ2=6.245, P=0.620); the model collinearity results showed that the variance inflation factors (VIF) values of each variable were <2, and there was no collinearity among the main indicators; the results of the individual independence test for the model showed that Durbin-Watson statistics (D-W)=0.279 and there was poor mutual independence among main indicators. ROC curve analysis showed that the area under the curve(AUC) of serum CD80 at admission in predicting the therapeutic effects of children was 0.762, the cut-off value was 2.390%, and the specificity, sensitivity and Youden index were 0.598, 0792 and 0.390 respectively; the AUC predicted by CD86 was 0.739, the cut-off value was 3.280%, and the specificity, sensitivity and Youden index were 0.510, 0.896 and 0.406 respectively; the AUC by combined prediction was 0.823, and the specificity, sensitivity and Youden index were 0.696, 0.833 and 0.529 respectively. Conclusions　Peripheral blood stimulating molecules CD80 and CD86 are involved in the progression of HFMD. Their overexpression may suggest a high risk of treatment ineffectiveness in children with severe HFMD. Early dynamic monitoring of the expression of serum CD80 and CD86 has a certain predictive value for the therapeutic effect of children.

Objective To evaluate the status of abnormal glucose metabolism in patients being alive over 3years after liver transplantation and discuss the possible mechanism of post-transplant diabetes mellitus ( PTDM ).Methods In this study, the clinical data of patients with liver transplantation were collected from April 2001 to December 2008. Patients with diabetes mellitus before operation and those who had died and failed to appear during follow-up were exluded. 199 patients living over 3 years after liver transplantation were follow-up. The prevalence of PTDM was evaluated according to fasting plasma glucose(FPG). Among those without diabetes according to FPG,32patients underwent 75 g oral glucose tolerance test (OGTT) , and fasting and 2 h plasma glucose and insulin were determined. 32 patients were divided into three groups [normal, impaired glucose regulation ( IGR ) , and PTDM groups], proportion of PTDM and homeostasis model assessment ( HOMA ) index were calculated. Results In patients alive over 3 years after liver transplantation, the prevalence of PTDM was 34.67% according to FPG. The OGTT result showed that the proportion of PTDM was 9.38%, IGR, including impaired fasting glucose(IFG) and impaired glucose tolerance ( IGT ) , was 56. 25% , while 34. 37% remained normal. The homeostasis model assessment β cell function index( HOMA-β ) decreased progressively from normal group, IGR group to PTDM group,and that in PTDM group was significantly lower than those in normal and IGR group( P＜0.01 ). IGR group had the highest homeostasis model assessment for insulin resistance (HOMA-IR) and PTDM group the next, and HOMA-IR in IGR group was significantly higher than normal group. Conclusion In patients alive over 3 years after liver transplantation, the prevalence of PTDM reached 44.05%. Insulin resistance existed during early period of impaired glucose regulation, while the degeneration of β cell progressed with the worsening of impaired glucose regulation.

Objective To evaluate the gender differences in neuromuscular blockade induced with rocuronium in patients undergoing abdominal surgery. Methods Twenty-four ASA Ⅰ or Ⅱ patients aged 20-59 yrs undergoing abdominal surgery under general anesthesia were enrolled in this study. Their body mass index (BMI) ranged between 18.5-25 kg?m-2. Patients with neuromuscular disease were excluded and no patient was taking any drug that might influence the effect of muscle relaxant. The patients were divided into male group ( n = 12) and female group (n = 12). The neuromuscular function was monitored and recorded using accelerography (DK-5210, Biometer, Denmark). The response of adductor pollicis muscle to train-of-four (TOF) stimulation of ulnar nerve were recorded. Body temperature was maintained at 36.0-36.9℃ and room temperature at 24-26℃ during surgery. The premedication included intramuscular atropine 0.01 mg?kg-1 and oral diazepam 10 mg. Anesthesia was induced with fentanyl 2-4 ?g?kg-1, propofol 2-3 mg?kg-1 and rocuronium 0.6 mg?kg-1. The patients were intubated and mechanically ventilated (VT = 7-10 ml RR = 12-14 bpm). PET CO2 was maintained between 35-45 mm Hg. Anesthesia was maintained with propofol by TCI (effect-site concentration was set at 3-4 ?g?ml-1) and intermittent i.v. boluses of fentanyl. Rocuronium (1 mg?ml-1) was infused and T1 was maintained at 5%-10% of the control height. At the end of surgery rocuronium infusion was terminated and neostigmine 0.05 mg?kg-1 was given i.v. .Results There were significant differences in body weight and height between male and female groups ( P

Abstract：In recent years，the outbreak and prevalence of respiratory infectious diseases in the world seriously endanger human health，among which the respiratory infectious diseases caused by viral infection account for a large proportion. The use of vaccines and common antiviral drugs is an effective way to fight viral infection，but there are also problems such as lag and drug resistance. Monoclonal antibodies against respiratory viral infections provide a new strategy for clinical treatment. This paper reviews the development of monoclonal antibody against respiratory virus and its application in respiratory viral infectious diseases.

Objective To investigate the regional homogeneity (ReHo) changes of primary insomnia (PI) with cognitive impairment using resting?state fMRI. Methods Twenty-one patients with primary insomnia and cognitive impairment and 25 healthy volunteers matched with age, gender and education level were collected from Southwest Hospital of China from November 2014 to June 2015. Pittsburgh sleep quality index (PSQI), Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE), Activity of Daily Living Scale (ADL), Hamilton depression scale (HAMD), and Hamilton Anxiety Scale (HAMA) were conducted to evaluate the sleep and cognitive conditions of all subjects. Independent sample t?test was performed to evaluate the significant difference of neuropsychology scores of two groups. ReHo of rs?fMRI were evaluated and compared between two groups using independent sample T?test, meanwhile, the partial correlation analysis was conducted in ReHo values of different brain regions and neuropsychology scores (age, gender and education level were regarded as covariates). Results Compared with normal controls, patients with primary insomnia and cognitive impairment showed significant higher PSQI score and lower MoCA and MMSE scores(P<0.05). The patient group also showed significant increased ReHo in the left medial temporal gyrus(54 voxels, t=3.14), left inferior temporal gyrus(76 voxels, t=4.80), right inferior temporal gyrus(84 voxels, t=4.30) and left parahippocampal gyrus(301 voxels, t=4.44) (P<0.05) and decreased ReHo in the left superior temporal lobe(79 voxels, t=-3.38), right fusiform gyrus(50 voxels, t=-3.17), right superior temporal gyrus(283 voxels, t=-5.34), right inferior frontal gyrus(56 voxels, t=-3.98), right anterior cingulate(233 voxels, t=-3.91), left parietal lobe angular gyrus(67 voxels, t=-3.27) and superior parietal lobule(65 voxels, t=-3.45) (P<0.05). The partial correlation analysis showed positive correlations between the ReHo values and PSQI scores of the left parahippocampal gyrus (R=0.771,P<0.01), negative correlations between the ReHo values and PSQI scores of the right anterior cingulate gyrus (R=-0.649,P<0.01) and positive correlations between the ReHo values and MoCA scores of the right anterior cingulate gyrus(R=0.555,P<0.05). Conclusions Patients with primary insomnia and cognitive impairment have ReHo alterations in various brain regions. The decreasing ReHo in the right anterior cingulate gyrus can reflect the level of sleep disorder and cognitive impairment, and increasing ReHo in the left parahippocampal gyrus can reflect the compensation of sleep disorders of PI.

BACKGROUND:Gelatin-chitosan-hydroxyapatite-minocycline biomimetic nanocomposite materials were developed in our previous studies. OBJECTIVE:To observe the capability of gelatin-chitosan-hydroxyapatite-minocycline biomimetic nanocomposite materials in the repair of rabbit radius defects. METHODS: Thirty healthy adult New Zealand rabbits were selected to make critical-size lacunar bone defects of the upper radius (15 mm×6 mm). Then, the rabbit models were randomized into experimental group (n=15), autogenous bone graft group (n=10) and blank group (n=5). Gelatin-chitosan-hydroxyapatite-minocycline biomimetic nanocomposite materials were implanted into radial bone defects in the experimental group. Bone defect in blank group was implanted without any materials; in the autogenous bone graft group, the contralateral radius with same length was taken and implanted into the defect. General observation, histological observation and X-ray observation were performed respectively at 2, 4, 8, 12 weeks postoperatively. RESULTS AND CONCLUSION:At 12 weeks after operation, the experimental group showed obvious new blood vessels at the defect region, complete bony union and disappearance of the composite implant, but lamelar bone structure appeared, smal blood vessels were visible, the edge of new bone was connected to the original bone edge, exhibiting a continuity of bone, the bone density was slightly lowered, and the defect region became unobvious. In the autogenous bone graft group, bony union and trabecular bone reconstruction were distinct, the lamelar bone became mature, the medulary cavity was recanalized, the fracture line disappeared completely, and the bone density was completely consistent with that of the original bone. In the blank group, there was no obvious bone formation, which led to bone nonunion, and there were a great amount of fiber tissues and inflammatory cel infiltrated. To sum up, the gelatin-chitosan-hydroxyapatite-minocycline biomimetic nanocomposite material can obviously promote the repair of critical-size bone defects, and the repairing effect is basicaly the same with that of autologous bone grafting.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.

Objective To investigate multiparametric immunophenotypic features in patients with acute myelocytic leukemia(AML)-M_2 bearing AML-1/ETO gene rearrangements and its predicting value.Methods A multiparametric flow cytometry was used in the study of phenotypic characterization of the subtype of AML.Immunophenotype of 30 patients with AML(M_2/ETO~+)was analyzed by fluorescence in situ hybridization(FISH).The results were compared with 36 patients of AML-M_2 with AML-1/ETO~- (M_2/ETO~-)and 34 acute promyelocytic leukemia(APL)patients.Results There were a population. 15.89%-68.53% the blast cell and a population of more differentiated and heterogeneous myeloid cells in the marrow of 30 patients with M_2/ETO~+.The blast cells had a myeloid phenotype(CD_(33),CD_(13)and MPO) and showed a characteristic pattern of antigen expression.The fluorescent intensity of CD_(33)in patients with M_2/ETO~+ was less than in patients with M_2/ETO~-and APL [ mean fluorescent intensity(MFI):98?75 v. 244?184 and 845?523,both P

Objective To analyze the CT findings of endobronchial spread in lung adenocarcinoma. Methods The CT findings of 15 lung adenocarcinomas or bronchioloalveolar carcinomas with endobronchial spread were reviewed,the distribution and the progression of the spread were evaluated.Results All of the primary tumors were consolidation form.The spread lesions distributed in one side of the lung or both sides along the bronchus.The pleural surface was spared.The CT findings of the spread included centrilobular nodules(n=5),tree-in-bud(n=7),acinar nodules(n=2),ground-glass opacities(n=10)and air- space consolidations(n=13)in the first CT examination.5 cases of the spread lesions only presented centrilobular nodules(single form)and 10 cases presented several appearances(complex form).All of the cases were diagnosed as tuberculosis or pneumonia,and antituberculotic or antibiotic therapy was taken with no effect.The follow-up CT scans showed progression in all cases,and the spread lesions with single form became multiple consolidations.The spread lesions with complex form deteriorated faster than the single one. Conclusion Although the CT findings of the endobronchial spread of the lung adenocarcinoma is specific, the clinical history and laboratory examination also are important for the differential diagnosis with tuberculosis and other infectious diseases.
