Objective To explore the diagnostic value of video bronchoscope-guide transbronchial needle aspiration(TBNA) combined with transbronchial lung biopsy(TBLB) on pulmonary sarcoidosis.Methods Twenty-two patients,definitely diagnosed as stage Ⅰ pulmonary sarcoidosis,were enrolled into the study and accepted TBNA and TBLB.Results The positive diagnostic rates of TBNA and TBLB were 63.6%(14/22) and 40.9%(9/22),but the rate increased to 90.9%(20/22) when the two methods were used together,which showed significant differences(x2=12.24,4.66,P＜0.01 or ＜0.05).Conclusion TBNA combined TBLB test is a safety method with high diagnostic accuracy for pulmonary sarcoidosis.

OBJECTIVETo investigate the flavonoids in Rhododendron mariae.

METHODThe constituents in R. mariae were determined by UPLC/Q-TOF-MS. The chromatographic separation was performed on a C18 column (2.1 mm x 50 mm, 1.7 microm) with a gradient elufion of methanol-water containing 0.1% formic acid. The mass specfrometer eqaipped with elecfrospay ionizafion source was usedas defecfor and operated in data was collected under the positive and negative ion modes.

RESULTSeven constituents were identified as myricetin-3-O-beta-D-gluconside (1), myricetin-3'-O-beta-D-xylopyraoside (2), hyperoside (3), isoquercitrin (4), avicularin (5), quercitroside (6) and quercetin (7).

CONCLUSIONIn this study, the main flavonoids in R. mariae were separated by UPLC, and identified through the information of positive ion and negative ion and relative molecular mass which were determined by Q-TOF-MS. It is an accurate and effective method which can be applied for the constituent identification of R. mariae.

Objective:To evaluate the efficacy and toxicity of single-agent bendamustine in patients with indolent B-cell non-Hodgkin's lymphoma (NHL) refractory to rituximab. Methods:Between April 2010 and April 2013, 100 patients with rituximab-refrac-tory indolent B-cell NHL from 8 institutions were enrolled. Bendamustine was administered at 120 mg/m2 on days 1 and 2 every 21 days for 6-8 cycles. The primary endpoint was the overall response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results:One hundred patients with a median age of 56 (rang-ing from 28 to 74) years were recruited in this clinical study. The total number of chemotherapy was 447 cycles, and the median number was 4 cycles. Ninety-three patients could be evaluated for efficacy. Fifteen patients (16.1%) had complete remission (CR), 52 (55.9%) had partial remission (PR), 22 (23.7%) had stable disease (SD), and 4 (4.3%) had progression disease (PD). The ORR and DCR were 72%and 95.7%, respectively. After a median follow-up of 26.6 months (ranging from 2 to 48.4 months), 59 patients (63.4%) had PD.The median PFS was 8.53 (95%CI:6.518-10.542) months, and PFS rate for 1 year was (40.6±5.3)%. Forty-eight patients (48%) had 3/4 grade adverse events, including leucopenia (26%), neutropenia (24%), and anemia (11%). Conclusion:Single-agent bendamustine produced a high rate of objective responses in patients with rituximab-refractory indolent B-cell NHL and could be one of the new op-tions for second-line treatment of these patients. The most common adverse event is hematologic toxicity.

With the continuous advancement of health informatization and the wide application of medical big data, electronic health records came into being and spread rapidly. However, because electronic health records contain a large amount of private information, privacy protection is the primary consideration for the sustainable development of electronic health records. By analyzing the shortcomings of privacy protection of electronic health records in law, technology, management and protection consciousness, this paper put forward some countermeasures, such as perfecting the relevant laws and regulations of privacy protection of electronic health records, improving the technical level, improving the management defects of electronic health records, and cultivating the privacy protection consciousness of professionals and the public, so as to improve the overall privacy protection level of China’s health records information management system and provide effective protection for the privacy information of Chinese residents’ electronic health records.

ObjectiveTo determine the epidemic characteristics of anthrax in Chengde City， Hebei Province from 2005 to 2021， and to provide evidence for formulating prevention and control measures of anthrax and reducing incidence rate. MethodsThis study collected the data of anthrax epidemic in Chengde City and conducted descriptive analysis. ResultsFrom 2005 to 2021， a total of 11 anthrax cases were reported in Chengde City with no death. The average incidence rate was 0.08/10⁵， which remained low. Furthermore， 10 cases were cutaneous anthrax and 1 case was pulmonary anthrax. The cases were mainly reported in Weichang County， accounting for 90.91% of the total reported cases， followed by Pingquan City. In addition， the cases were mainly reported from July to August and mainly between 30 and 59 years old with a gender ratio of 2.67∶1. ConclusionThe anthrax epidemic in Chengde City is likely to increase. It mainly occurs in summer， rural areas， and male young and middle-aged farmers. It is necessary to improve epidemic monitoring， health education， disease prevention capacity， early identification of the epidemic， and active response.

ObjectiveTo analyze the mental health status of non-psychiatric inpatients in a general hospital， and to explore the relevant influencing factors， so as to provide references for the screening of mental health problems and the construction of intervention models among non-psychiatric inpatients. MethodsA cross-sectional study was conducted among 916 non-psychiatric inpatients in a third grade class A general hospital in Guangzhou， and all the inpatients were assessed using Patient Health Questionnaire-9 item （PHQ-9）， Generalized Anxiety Disorder-7 item （GAD-7）， Athens Insomnia Scale （AIS） and Columbia-Suicide Severity Rating Scale （C-SSRS） to detect their depression， anxiety， insomnia and suicide risk status. Thereafter， univariate and multivariate Logistic regression analysis were used to screen the risk factors affecting the mental health of inpatients. ResultsA total of 339 （37.0%） inpatients with positive mental health problems were screened， and the screening results for each dimension revealed 218 cases （23.8%） of depression， 141 cases （15.4%） of anxiety， 257 cases （28.1%） of insomnia， 42 cases （4.6%） of suicidal ideation and 7 cases （0.8%） of suicidal behavior. Binary Logistic regression analysis showed that female （OR=1.379， P<0.05） was a risk factor for positive screening of mental health problems. Ordinal Logistic regression analysis denoted that age above 60 years old （OR=1.542， P<0.05） and singlehood （OR=2.055， P<0.05） were risk factors affecting the severity of depression， while senior high school to junior college education （OR=0.524， P<0.05） was a protective factor of depression， meantime， female （OR=1.472， P<0.05） was a risk factor affecting the severity of insomnia. ConclusionMental health problems are quite common among non-psychiatric inpatients in general hospitals， and are mainly affected by factors such as gender， age， marital status and educational background.
