Objective To explore the clinical effect of intravenous immunoglobulin(IVIG)on chronic obstructive pulmonary disease(COPD)and fungal infection.Methods Seventy-two COPD patients with fungal infection were randomly and equally divided into conventional and intervention group.Patients in conventional group were treated with common schedule for COPD plus antifungal agents;patients in intervention group received 1 0 g/d IVIG besides routine therapy.Length of hospital stay and prognosis were recorded,and therapeutic effectiveness were evaluated. Results The effectiveness rate of intervention group was significantly higher than that of conventional group ([88.89%,32/36]vs [66.67%,24/36]);the average length of hospital stay was significantly shorter than conven-tional group ([12.62±7.51]d vs [20.81±6.92]d),and mortality was lower than conventional group ([5.56%, 2/36]vs [22.22%,8/36]),the differences were statistically significant (P<0.05).Conclusion IVIG for treating COPD with invasive pulmonary fungal infection can improve therapeutic efficacy,shorten length of hospital stay and decrease mortality rate.

Objective To evaluate the role of 5-HT1A receptors in distal cerebrospinal fluid (CSF)-contacting neurons in neuropathic pain (NP) in rats. Methods Forty male SD rats weighing 230-270 g were randomly divided into 4 groups (n = 8 each): sham operation group (group S); NP group; dimethyl sulfoxide (DMSO) group and 8-OH-DPAT (a specific 5-HT1A receptor agonist) group. NP was induced by chronic constrictive injury (CCI) in groups NP, DMSO and 8-OH-DPAT. Four silk ligatures were placed on the sciatic nerve at 1 mm intervals . In group S, the sciatic nerve was exposed but not ligated. 8-OH-DPAT and DMSO 1 μl were injected into the region where most of CSF-contacting neurons are present over 5 min on 7th day after CCI in groups 8-OH-DPAT and DMSO respectively. Paw withdrawal latency (PWL) and paw withdrawal threshold (PWT) were measured before CCI, on 7th day after CCI, and at 3 and 6 h after administration. The rats were sacrificed 6 h after administration, and the brain tissues removed for determination of the expression of 5-HT1A receptors in the distal CSF-contacting neurons by immunofluorescence. Results Compared with group S, PWL was significantly shorten and PWT decreased at T, in groups NP, DMSO and 8-OH- DPAT (P ＜ 0.01) . Compared with group DMSO, PWL was significantly prolonged and PWT increased at T2 and T3 in group 8-OH-DPAT ( P ＜ 0.01). The 5-HT1A receptor expression was significantly down-regulated in groups NP and DMSO compared with group S, while up-regulated in group 8-OH-DPAT compared with groups NP and DMSO ( P ＜ 0.01). There was no significant difference in 5-HT1A receptor expression between groups NP and DMSO ( P ＞ 0.05). Conclusion 5-HT1A receptors in distal CSF-contacting neurons are involved in the regulation of NP in rats.

Objective To evaluate body surface localization by virtue of lnnova CT reconstruction combined with DSA guidance in performing percutaneous fine needle biopsy of lung lesions. Methods Twenty-one patients with solid lung lesions were enrolled in this study. Before percutaneous lung needle biopsy, DSA rotation scanning was performed. Based on the reconstructed lnnova CT images, precise puncture scheme was formulated. Then, under DSA guidance, pereutaneous fine needle biopsy of lung lesions was carried out. Results A total of 41 percutaneous fine needle biopsies was made, of which definite pathologic diagnosis was obtained in 40, with a positive rate of 97.6%. Pneumothorax occurred in one patient (4.8%). Conclusion Percutaneous lung needle biopsy with the help of body surface localization, which is determined by Innova CT reconstruction images, and DSA guidance is a safe and technically-simple procedure with high accuracy in localization. It is of great value in the diagnosis of pulmonary space-occupying lesions.

Objective To summarize MSCT manifestations of normal small bowel with oral water and colon water enema double-filling. Methods Small bowel parameters of 44 healthy volunteers were measured with oral water and colon water enema double-filling. The parameters included bowel wall thickness, diameter of filling bowel, bowel wall delamination, bowel wall CT attenuation, the number of the plica, the attenuation of mesenteric fat, mesenteric vessels, the appearance rate of lymph node in mesentery, retroperitoneum, and so on. Results The average bowel thickness was (1.72±0.20) mm; the average diameter of filling bowel was (21.24±3.05) mm; the average CT attenuation of plain scan, artery phase and portal phase was (28.13±0.38) HU, (55.42±0.88) HU and (67.86±0.94) HU. Jejunum plica of normal small intestine was 2.29/cm; the number of the mesenteric artery bowel was 2.59/cm; the average attenuation of mesenteric fat was-98.57 HU; the single layer of bowel changed mostly. Conclusion Proper knowledge of normal manifestations of small bowel on MSCT is helpful for the diagnosis of small bowel diseases.

Objective To investigate the risk factors of hypersensitivity induced by compound sulfamethoxazole (Co-SMZ)in patients with human immunodeficiency virus (HIV)infection.Methods A retrospective study was performed in 111 patients with HIV infection receiving prophylactic Co-SMZ at the Department of Infectious Diseases,the Third People′s Hospital of Nantong City,Jiangsu Province from January 2014 to December 2014.Data including age,gender,interval time from diagnosis of HIV infection to hospitalization,history of drug allergy,and the counts of CD3 + T cell,CD4 + T cell,CD8 + T cell and natural killer (NK)cell on the day when the medicine was administrated for the first time were recorded. All the patients were followed up for two months.Student t test was used in data with normal distribution or approximate normal distribution.Rank sum test was used in data with skew distribution.The count materials were examined byχ2 test.Results Among the 111 patients with HIV infection,there were 107 males and 4 females with average age of (45 .7±11 .1)years old.The interval time from taking Co-SMZ to hypersensitivity was (14.0±7.6)d.There were differences in the counts of CD4 + T cell and NK cell between patients with hypersensitivity and without hypersensitivity (both P <0.05).Multivariate analysis showed that NK cell was a risk factor for inducing hypersensitivity (OR=1 .010,95 %CI :1 .005 -1 .017, P =0.001).The area under of receiver operating characteristic curve predicting hypersensitivity induced by Co-SMZ was 0.748 (95 %CI :0.647-0.850,Z =4.701 ,P =0.001).The best predictor was 109.80/μL with sensitivity of 63.2% and specificity of 84.7%.Conclusion In patients with HIV infection,NK cell might be associated with hypersensitivity induced by Co-SMZ.

Objective To prepare a novel nano-suspension of niclosamide ethanolamine and evaluate its molluscicidal effect. Methods Niclosamide ethanolamine and stabilizing agent—polyvinylpyrrolidone (PVP) were dissolved in dimethyl sulfoxide. After the solution was added into water under fast stirring, niclosamide ethanolamine was quickly precipitated to form nanoparticles and nano-suspension was obtained. The weight ratio of PVP to niclosamide ethanolamine, concentration, temperature, stirring speed on the size and distribution of the nanoparticles were investigated. The molluscicidal effect of niclosamide ethanolamine nano-suspension was measured by immersion and spray methods in the laboratory and field. Results When the weight ratio of PVP to niclosamide ethanolamine was from 1∶2 to 1∶3, the nanoparticles of the niclosamide ethanolamine had diameters about 100 nm and the nano-suspension was stable without agglomerating for more than 1 month; as the speed of the stirring increased, the nanoparticles prepared became smaller and more stable. LC50 of the nano-suspension was 0.0544 mg/L but the LC50 of wettable powder of niclosamide ethanolamine salt (WPN) was 0.1250 mg/L. In the field immersion and spray tests, the concentration of nano-suspension as only 1/5 of active content of WPN achieved the same molluscicidal effect with WPN. Conclusions The nano-suspension has higher molluscicidal effect than WPN and the novel formulation of niclosamide has more advantages than WPN, it is useful for snail control in the field.
