Objective: To investigate the therapeutic effect of combination of acupuncture and medicine in treating allergic rhinitis. Methods: Acupuncture, moxibustion, nasal inhalation and oral administration of Chinese materia medica were used as a composite treatment for different constitutions. The relations of the patient's age, syndrome type and course of disease to the therapeutic effect were investigated. Results: Among the treated 92 cases, marked effectiveness occurred in 68, effectiveness in 16 and ineffectiveness in 8, with a total effective rate of 91.3%. The therapeutic effect was not good in the patients who belonged to dry heat in lung meridian type and had the course of disease for more than 20 years. Conclusion: A combination of acupuncture and medicine has an exact therapeutic effect on allergic rhinitis.

Objective To better understanding the clinical presentations of phaeohyphomycosis,and improve the diagnosis and management of the disease.Methods We reported a case of pulmonary phaeohyphomycosis caused by Exophiala jeanselmei at the First Affiliated Hospital of Guangzhou Medical University in 2008,and reviewed the relevant literature.The clinical,radio-logical and etiological features were summarized based on this case and the other 23 phaeohyphomycosis patients reported in China from January 1995 to August 2013.Results 24 Chinese cases of phaeohyphomycosis have been reported to date,including 15 males and 9 females.The age of these patients ranged from 4 to 76 (mean 40.0±21 .8)years old.Seventeen patients were otherwise healthy.The other 7 patients had complications.Clinical presentations of phaeohyphomycosis vary widely,including cutaneous and subcutaneous infection in 18 cases,pulmonary and central nervous system involvement in two cases each,para-nasal sinus and palpebral conjunctiva infection one case each.The diagnosis of 18 cases were confirmed both microbiologically and histologically.One case was confirmed histologically alone.Five cases were identified microbiologically alone.The samples for culture were collected from skin abscess (1/5 ),pulmonary tissue (2/5 ),and cervical spinal fluid (2/5 ),respectively. Twenty-two strains of causative organisms were identified,7 of which were Exophiala jeanselmei .Twenty-three patients received treatment.They were cured by antifungal agents alone (18)or in conjunction with surgical resection (4 ),or assisted with XD-635AB-based photodynamic laser therapy (1).Specifically,10 pa-tients were cured by itraconazole alone.Conclusions In China, most patients of phaeohyphomycosis have concurrent conditions or have previously received immunosuppressive agents and cor-ticosteroids.Cutaneous and subcutaneous infection were most common,located mainly on limbs,face,chest and abdominal skin.The most frequently isolated pathogen is Exophiala jeanselmei ,followed by Phialophora verrucosa and Exophiala spinifera .Itraconazole therapy would be very effective.Susceptibility testing is very useful in case of refractory infection.

Objective To evaluate effects of interleukin-36α (IL-36α) on psoriasiform skin lesions and C-C motif chemokine ligand 20 (CCL20) expression in mice.Methods Totally,30 BALB/c female mice were randomly and equally divided into 3 groups:control group treated with topical vaseline cream on the shaved back and intracutaneous injection with phosphate buffer saline (PBS),model group treated with topical imiquimod cream on the shaved back and intracutaneous injection with PBS,experimental group treated with topical imiquimod cream on the shaved back and intracutaneous injection with IL-36α solution.Psoriasis area severity index (PASI) was used to evaluate changes of psoriasiform skin lesions in mice,and light microscopy to observe morphological changes of skin lesions and to measure the thickness of the epidermis.Real-time fluorescence-based quantitative PCR (qRT-PCR) and Western blot analysis were performed to determine the expression of IL-36α in skin lesions in the control group and model group,and qRT-PCR,Western blot analysis and immunohistochemical study to evaluate changes of CCL20 levels in skin lesions.Results The model group showed significantly increased mRNA (△ Ct value:0.0195 ± 0.0059) and protein expression (3.922 ± 0.248) of IL-36α compared with the control group (mRNA:0.0012 ± 0.0004,P ＜ 0.05;protein:0.690 ± 0.025,P ＜ 0.05).The mRNA and protein expression of CCL20 were significantly higher in the experimental group than those in the model group (mRNA:2.152 ± 0.793 vs.0.999 ± 0.178;protein:0.397 ± 0.033 vs.0.145 ± 0.030;both P ＜ 0.05),and higher in the model group than those in the control group (mRNA:0.378 ± 0.075;protein:0.025 ± 0.009;both P ＜ 0.05).Immunohistochemical study showed that the expression intensity of CCL20 in skin lesions significantly increased in the experimental group compared with that in the model group (Z =2.294,P ＜ 0.05).Conclusion IL-36α may aggravate psoriasiform skin inflammation in mice by promoting CCL20 expression.

【Objective】 To investigate the current situation concerning volume control of red blood cells in additive solution produced by blood service in Chongqing, and to lay a foundation for promoting the homogenization of preparation process of red blood cells in additive solution. 【Methods】 A questionnaire was designed to investigate the factors related to the preparation of red blood cells in additive solution. The questionnaire was sent by Chongqing Association of Blood Transfusion via E-mail to 18 blood services in the city, and the collected data was sorted, revised and analyzed by research team. 【Results】 A total of 18 blood services(including 1 blood center + 1 sub-center, 6 central blood stations and 11 central blood banks) returned the questionnaires. The results showed that there were differences among blood services across Chongqing, regarding the centrifugal parameters during preparation, the operation mode and monitoring situation of the capacity control during preparation, and the formulation of the capacity standard of red blood cells in additive solution etc. 【Conclusion】 The preparation process of red blood cells in additive solution, produced by Chongqing blood services, should be further standardized, and the capacity control method of this product in Chongqing should be gradually unified to achieve regional homogeneity and to ensure blood safety.

Objective:To explore whether the adoption of high-flow nasal cannula (HFNC) as an initial oxygen therapy in emergency department (ED) could reduce the intubation rate and improve the clinical outcomes of patients with dyspnea and hypoxemia compared with conventional oxygen therapy (COT).Methods:A perspective single-center randomized controlled trial was conducted in the First Affiliated Hospital of Zhengzhou University from October 1, 2019 to September 30, 2020. A total of 210 eligible patients with acute dyspnea and hypoxemia in ED were recruited and randomized (in 1:1) to receive HFNC or COT for 1 h immediately after the grouping. The primary outcome was the rate of intubation within 24 h. The secondary outcomes included total intubation rate, escalation of breathing support method, patients’ disposition, length of ICU stay and hospital mortality. Continuous outcomes were analyzed by independent samples t test or Mann-Whitney U test according to the data distribution. Discontinuous outcomes were compared with the Chi-square test. Kaplan-Meier curve analysis was performed for 60-day survival. Results:Finally, 105 patients were recruited in each group. HFNC reduced the intubation rate within the first 24 h (4.8% vs. 14.3%, P = 0.019) and the rate of patients escalated to upgrade oxygen therapy (34.3% vs. 53.3%, P = 0.005), but did not affect the total intubation rate during the whole attendance ( P = 0.509). In ED, HFNC helped more patients to achieve the targeted saturation of pulse oxygen (90.5% vs. 78.1%, P = 0.02), and reduced respiratory rate (RR) to < 25 breaths per min (68.6% vs. 49.0%, P = 0.004), but did not affect the length of hospital stay, hospital mortality and 60-day survival rate ( P > 0.05). Conclusions:Initial application of HFNC in ED could reduce the intubation rate within 24 h, decrease the rate of escalation of oxygen therapy, improve oxygenation and relieve dyspnea.
