Objective To investigate clinical characteristics of relapsing polychondritis(RP)and to improve early recognition for it.Methods Clinical and laboratory data of 56 patients with RP were analyzed retrospectively.Results Ratio of number of male patients to female ones was 1.2.Age at onset was(46?11)years(ranging from 27 to 71)and average interval between onset and diagnosis was(21? 35)months,(8?6),(16?31)and(29?37)months for patients initial onset with auricle,respiratory tract and joints involved,respectively.Site involved included airway in 40 patients(71.4%),auricle in 32 (57.1%),joints in 32(57.1%),eyes in 27(48.2%),nasal chondritis in 25(44.6%)and inner ear in 13(23.2%).At initial stage of the course,17 patients were misdiagnosed as respiratory infection (30.4%),nine as perichondritis(16.1%),six as pulmonary tuberculosis(10.7%),five as rheumatoid arthritis(8.9%).Seven of 40 patients with airway involvement received metallic stents for their tracheobronchial stenosis.Four patients whose condition never improved after regular therapy all had respiratory involvement.Conclusions Patients of RP with initial onset at non-auricle,non-nasal sites tended to be misdiagnosed.Prevalence of airway involvement was not so low with a poor prognosis in patients of RP.

Abstract: Objective To analyze a case of bloodstream infection caused by Ureaplasma urealyticum after abortion in Anxi County Hospital, so as to provide basis for the clinical diagnosis and treatment. Methods　The diagnosis of Ureaplasma urealyticum in this patient with bloodstream infection was retrospectively analyzed. The basic clinical data and laboratory diagnosis data were collected, including the characteristics of blood culture curve, Wright staining of culture medium, drug sensitivity of Mycoplasma liquid identification, colony characteristics of solid medium, and the conclusion of targeted DNA sequencing. Through the comprehensive analysis of the above data, the rapid diagnosis of this case can be realized by optimizing the detection and diagnosis process. Results　The clinical manifestations of this patient were fever of 38.5 ℃, CRP:14.85 mg/L, WBC:14.33×109/L, NET: 85.40%, PCT: 0.12 ng/mL, IL-6: 665.6 pg/mL, positive after 3 days of blood culture, no bacteria were found in Gram stain, and sand-like purple bacteria were observed after adding Wright's stain. After inoculation in blood agar, Mycoplasma solid and liquid medium, no colonies were grown in blood agar, after 48 h and 5 d. On Mycoplasma A7 agar, the edge of brown fried egg colony was striature, and it could be identified as Ureaplasma urealyticum with the Mycoplasma ID & AST panel, which was resistant to quinolones and spectinomycin, but sensitive to macrolides, tetracyclines and lincomycin. Subsequent targeted DNA sequencing results were also confirmed for Ureaplasma urealyticum. Before receiving the report, clinical experience treatment with ceftriaxone metronidazole was used to fight infection with negative bacilli and anaerobic bacteria. Mycoplasma was not treated with targeted treatment. After 3 days, the patient's body temperature returned to normal, inflammation index decreased, and the patient asked to be discharged. Conclusions　At present, there are few reports of bloodstream infection caused by Ureaplasma urealyticum, and the lack of clinical understanding can easily lead to misdiagnosis and missed diagnosis. In order to improve the detection rate of Mycoplasma in blood culture, it is necessary to optimize the detection procedure of blood culture and provide accurate diagnosis and treatment basis for clinical practice. However, it is clear from this case that Mycoplasma bloodstream infection cases are self-limited infection and can recover by themselves without targeted treatment in patients with normal immunity. Therefore, it is very important to protect the immunity of patients.

OBJECTIVETo investigate the effect and mechanism of Shenqi Fuzheng Injection (SFI) in repairing immune function of organism at cellular and molecular levels.

METHODSSeventy-seven patients with pathologically confirmed diagnosis of breast cancer were assigned to three groups, the 22 patients in group A received surgical operation only; the 26 in group B were treated with surgical operation and chemotherapy; and to the 29 in group C, both chemotherapy and SFI were given after surgical operation. Besides, a group D with 22 patients with benign tumor was set up for control. The protein expressions of CD83, CD80 and CD86 in all patients' tumor tissue and axillary lymph node were detected by flow cytometry before and after treatment.

RESULTSLevels of CD83, CD80 and CD86 in both tumor tissue and lymph node of cancer patients were significantly lower than those in the control (P < 0.05); and those in group B were significantly lower than in group A (P < 0.05, P < 0.01); but no significant difference was found in comparing the corresponding indices between group A and group C (P > 0.05).

CONCLUSIONThe immune function of tumor patients could be impaired by tumor and chemotherapy definitely, and SFI could give aid to the repairing of immunity by way of participating in the activation of dendritic cells and the up regulation of co-stimulus molecules.

To increase drug concentration in the head through intranasal administration, we have investigated the excised animal nasal mucosa permeability and nasal toxicity of the baicalin drug carrier systems, such as baicalin liposomes, beta-cyclodextrin inclusion compound, and phospholipid complex. A transport of baicalin drug carrier systems through nasal mucosa was simulated in diffusion chamber in vitro, and swine, caprine and rabbit nasal mucosa was used, the concentration of drug in the receptor was determined by HPLC. By taking the apparent permeability coefficients as evaluation standard, investigated the isolated animal nasal mucosa permeability of different baicalin drug systems was investigated for screening the best baicalin drug carrier system through nasal cavity administration. Toxicity of baicalin and its phospholipids complex on toad palate mucosal cilia movement and rats nasal mucosa long-term toxicity were studied in vivo. The apparent permeability coefficient of three kinds of baicalin drug carrier systems was better than that of baicalin (P < 0.05), and its lag-time was obviously shortened. At the same time, the apparent permeability coefficient of phospholipid complex was higher than those of other two drug carrier systems (P < 0.05). The results showed that the baicalin phospholipids complex nasal mucosa permeability was obviously superior to the other two drug systems. Baicalin phospholipids complex had no toxicity to ciliary movement, and had no irritation to rat nasal mucosa. The results show that baicalin phospholipid complex was the best baicalin drug carrier system, it could significantly enhance the permeability of baicalin across nasal mucosa, had no toxicity to nasal mucosa, and could be used for intranasal administration.
