OBJECTIVE: This study aimed to determine the HIV-1 subtype distribution and HIV drug resistance (HIVDR) in patients with ART failure from 2014 to 2020 in Hainan, China. METHODS: A 7-year cross-sectional study was conducted among HIV/AIDS patients with ART failure in Hainan. We used online subtyping tools and the maximum likelihood phylogenetic tree to confirm the HIV subtypes with pol sequences. Drug resistance mutations (DRMs) were analyzed using the Stanford University HIV Drug Resistance Database. RESULTS: A total of 307 HIV-infected patients with ART failure were included, and 241 available pol sequences were obtained. Among 241 patients, CRF01_AE accounted for 68.88%, followed by CRF07_BC (17.00%) and eight other subtypes (14.12%). The overall prevalence of HIVDR was 61.41%, and the HIVDR against non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleotide reverse transcriptase inhibitors (NRTIs), and protease inhibitors (PIs) were 59.75%, 45.64%, and 2.49%, respectively. Unemployed patients, hypoimmunity or opportunistic infections in individuals, and samples from 2017 to 2020 increased the odd ratios of HIVDR. Also, HIVDR was less likely to affect female patients. The common DRMs to NNRTIs were K103N (21.99%) and Y181C (20.33%), and M184V (28.21%) and K65R (19.09%) were the main DRMs against NRTIs. CONCLUSION The present study highlights the HIV-1 subtype diversity in Hainan and the importance of HIVDR surveillance over a long period.

OBJECTIVE: To investigate the impact of a history of atopy on the value of fractional exhaled nitric oxide (FENO) for predicting sputum eosinophils in patients with chronic cough. METHODS: A total of 868 patients with persistent cough lasting more than 3 weeks without pulmonary infection were enrolled, including 119 patients with subacute cough (defined as cough lasting 3-8 weeks) and 749 with chronic cough (longer than 8 weeks). The predictive value of FENO level for sputum eosinophilia was analyzed using receiver-operating characteristic (ROC) curve analysis, and the area under the curve (AUC) was calculated. The atopy status of the patients was determined by screening for history of allergy, hay fever, or animal or food allergies. RESULTS: Of the 868 patients enrolled, 173 patients (19.9%) had eosinophilic airway inflammation (EAI). In the overall patients, the median (Q1, Q3) FENO level was 18 (12, 35) ppb, ranging from 5 to 300 ppb. The patients with chronic cough and a positive history of atopy had a higher median FENO level than those without atopy (24 [13, 50] vs 18 [11, 34]; Z=2.25, P= 0.029), and FENO level was significantly correlated with EAI (r=0.281, P < 0.001). The AUCs of FENO for diagnosis of airway eosinophilia in patients with atopy and those without atopy were 0.677 (95% CI: 0.548-0.806) and 0.708 (95% CI: 0.660-0.756), respectively. The optimal cut-off value of FENO for diagnosing EAI was higher in patients with atopy than in those without atopy (72 vs 28.5 ppb). CONCLUSION A history of atopy reduces the predictive value of FENO level for EAI in patients with chronic cough, suggesting the importance of examining the atopic status when interpreting test results of FENO.

Objective:To observe the effects of Albiziae Flos （AF） and Polygalae Radix （PR） alone and their combination on the improvement of depression-like behavior in rats with chronic unpredictable stress （CUS） as well as on hippocampal ultrastructure and the expression of cyclic adenosine monophosphate response element binding protein （CREB） and nicotinamide adenine dinucleotide phosphate oxidase 2 （NOX2）， to explore their action mechanisms. Method:Seventy-two Wistar rats were randomly divided into the normal group， model group， AF group， PR group， AF-PR group， and fluoxetine group. Rats in all groups except for the normal group were exposed to CUS and separated feeding to induce depression. Since the first day of modeling， rats in the AF group， PR group， AF-PR group were provided with the corresponding decoction containing 1.05 g·kg^-1 total crude drug by gavage， the ones in the fluoxetine group with 2.1 mg·kg^-1 fluoxetine hydrochloride aqueous solution， and those in the normal group and model group with the distilled water， for 28 successive days. The open field test and forced swimming test were performed 1 d before modeling and 7， 14， 21， 28 d after modeling， respectively. The morphological changes in hippocampus were observed under an electron microscope on the 28^th day. The superoxide dismutase （SOD） and malondialdehyde （MDA） levels in hippocampus were detected by ultraviolet spectrophotometry， and the expression levels of CREB and NOX2 were detected by real-time polymerase chain reaction （Real-time PCR） and Western blot. Result:The behavioral experiment results showed that the number of horizontal activities and sugar water consumption in the model group declined as compared with those in the normal group， while the immobility time in the forced swimming test was prolonged （P<0.05， P<0.01）. Compared with the model group， the AF group， PR group， and AF-PR group exhibited elevated number of horizontal activities， increased sugar water consumption but shortened immobility time in the forced swimming test （P<0.05， P<0.01）. Compared with the AF group or PR group， the AF-PR group showed significantly different behavioral indexes （P<0.05）. Morphological results showed that the mitochondria of the model group were obviously swollen and the ultrastructure of the hippocampus was destroyed. By contrast， the hippocampal ultrastructure in each administration group was close to normal. The comparison with the normal group revealed that the activity of SOD in the hippocampus of the model group was significantly reduced， whereas the content of MDA was elevated （P<0.01）. Compared with the model group， the AF group， PR group， and AF-PR group displayed increased activity of SOD and decreased content of MDA in the hippocampal tissues （P<0.05， P<0.01）. Compared with AF or PR alone， the herbal pair AF-PR resulted in significant differences in the above-mentioned indexes （P<0.05， P<0.01）. The results of Real-time PCR and Western blot demonstrated that NOX2 expression in the hippocampus of the model group was up-regulated in comparison with that in the normal group， while the CREB expression was down-regulated （P<0.05， P<0.01）. Compared with the model group， the AF group， PR group， and AF-PR group all showed diminished NOX2 expression but elevated CREB expression in the hippocampal tissues （P<0.05， P<0.01）. The protein expression levels of NOX2 and CREB in the AF group or PR group were significantly different from those in the AF-PR group （P<0.01）. Conclusion:AF and PR alone and their combination improve the depression-like behavior of rats exposed to CUS， which may be related to the reduction of oxidative stress， the up-regulation of CREB expression， and the down-regulation of NOX2 expression in hippocampus.

Objective To investigate the current situation in Chinese rheumatologic physicians' clinical diagnosis and evaluation of Takayasu's arteritis (TA).Methods Nineteen rheumatology experts and three vascular surgery specialists in China were invited to make the nationwide investigation for the first time about the diagnosis and disease activity evaluation of TA in China,through the questionnaire survey on the internet.Weighted average was used to calculate the average scores of corresponding problems.Results Chinese experts mainly adopted 1990 American College of Rheumatology (ACR) classification criteria for clinical diagnosis of TA.In details,symptoms of age,limb claudication and amaurosis,signs including pulselessness or pulse weakening,vascular bruits,increasing bilateral pulse pressure and hypertension and acute phase reactants (APR) were critical to the clinical diagnosis of TA.Besides,noninvasive imaging examinations,such as computed tomography angiography (CTA),magnetic resonance angiography (MRA),vascular ultrasonography,and positron emission tomography (PET) were also of great importance.In the aspect of disease activity assessment,Chinese experts mainly used Kerr scoring tool.APR and noninvasive radiological examinations were considered with vital value.Some TA patients with carotid artery involvement were recommended using vascular ultrasonography,while others with pulmonary artery and thoracic/abdominal aorta trunk involvement were preferred CTA other than MRA.Conclusions APR and noninvasive imaging examinations were thought with great help to make clinical diagnosis and evaluation of TA for Chinese physicians.

OBJECTIVETo analyze the composition and control status of chronic diseases among rural residents in a Beijing suburb district.

METHODSRural residents aged 35 years or older were investigated by stratified random sampling in Pinggu District, Beijing. Each participant received questionnaire-based survey,physical examination,and laboratory tests including routine blood test,urine albumin creatinine ratio (ACR), liver and renal function,serum lipid, fasting blood glucose, and glycosylated hemoglobin.

RESULTSA total of 10 385 residents completed all items. Cerebrovascular disease was leading cause of hospitalization (accounting for 14.4%) and its incidence in the population was 9.6%. The incidences of hypertension,hyperlipidemia,diabetes mellitus,and gout/hyperuricemia,which were the main compositions related with metabolic diseases,were up to 64.4%,42.5%,24.4%, and 9.0%, respectively. The disease onset was significantly related with the age. The incidence of hypertension was gradually elevated with the increasing of age,while the peak age was 55-64 years for diabetes and 35-44 years for gout/hyperuricemia. The awareness rate of hypertension,diabetes,and chronic kidney disease was 60.2%, 55.1%,and 6.0%,respectively. The control rate of chronic disease was 19.2% and 28.8% in hypertensive and diabetic patients, respectively.

CONCLUSIONSCerebrovascular diseases and metabolic-associated diseases are the main chronic diseases affecting rural residents in Pinggu district, Beijing. The awareness rate and control rate of chronic diseases needs to be further enhanced by strengthening health education and improving the community medical service.

The output and agronomic characters of 3-year-old Panax notoginseng cultured under stereo structure (upper, middle and down layers) were investigated, and the annual change of N, P and K of its planting soil were also studied. Results showed that, compared with field cultured Panax notoginseng, growth vigour and output of stereo-cultivation were significantly lower. But the total production of the 3 layers was 1.6 times of field. The growth vigor and production of P. notoginseng was in the order of upper layer > middle layer > down layer. The content of ginsenoside in rhizome, root tuber and hair root of P. notoginseng was in the order of upper layer > field > middle layer > down layer. Organic matter content and pH of stereo-cultivation soil decreased with the prolonging of planting time, which with the same trend of yield. Organic matter content of stereo-cultivation soil was significantly higher than field, but the pH was significantly lower. Contents of total and available N, P and K in stereo-cultivation soil and field decreased with the prolonging of planting time. The content of N and P were in the order of upper layer > middle layer > yield > down layer, the content of K was in the order of upper layer > middle layer > down layer > yield. Compared with field, the proportion of N and P in the organ of underground (rhizome, root tuber and hair root) of upper layer were increased, while decreased in middle and down layers. Proportion of K in underground decreased significantly of the 3 layers. In conclusion, the agronomic characters and production of stereo-cultivation were significantly lower than that of yield. But the total production of the 3 layers were significantly higher than field of unit area. And the aim of improving land utilization efficiency was achieved. Nutritions in the soil of stereo-cultivation were enough to support the development of P. notoginseng, which was not the cause of weak growth and low production. The absorbing ability of P. notoginseng to N, P and K nutrients was decreased by stereo-cultivation mode. So, improve the growth vigour of P. notoginseng from the perspective of adjusting the stereo-cultivation mode so as to improve the nutrient absorption capacity is the future direction.
