ABSTRACT
ObjectiveTo analyze the interannual fluctuation， seasonal fluctuation， habitat distribution and the correlation of the 3 monitoring indicators of Aedes albopictus in Yangpu District of Shanghai from 2017 to 2021， and to provide a scientific basis for A. albopictus control and rational use of the indicators. MethodsThe density surveillance data of A. albopictus recorded by Breteau index （BI）， Path index （PI） and the mosquito ovitrap index （MOI） from 2017 to 2021 in Yangpu District， Shanghai were compared. Microsoft Excel 2019 software was used for data summary and SPSS 25.0 software was used for statistical analysis. ResultsFrom 2017 to 2021， there were two months with BI>5， and the PI were all above the density control level of Class C， and there were nine months with MOI≥5. In 2017， BI was higher than in the other four years， with statistically significant differences （all P≤0.001）. MOI in 2017 and 2020 was higher than in 2019 （P=0.029， P=0.004） and 2021 （P=0.005， P=0.001）， with statistical significance. MOI for different types of habitats varied significantly， with a statistically significant difference （P=0.004）. A linear correlation was observed between BI and PI （r=0.462， P=0.010）. ConclusionBI， PI and MOI are used simultaneously to reflect the density of A. albopictus in Yangpu District of Shanghai. However， these three monitoring indicators show poor linear correlation. Comprehensively considering the scientific aspects of monitoring methods and seasonal fluctuations of indicators， it is suggested that MOI should be used as the main index to evaluate the density of A. albopictus. In the MOI， attention should be paid to factors such as the distribution of the habitats， the standardization of operating methods， and quality control， which are essential for enhancing the reliability of the MOI.
ABSTRACT
ObjectiveTo investigate the infection and genotypes of Wolbachia in Aedes albopictus. MethodsAdult and larval samples of Aedes albopictus were collected from different residential and wild areas from 2020 to 2021， Wolbachia surface protein （wsp） gene was amplified and genotyped for wAlbA and wAlbB by PCR， and sequenced for phylogenetic analysis. The difference of detection rate among different habitats， male and female adult mosquitoes， adult and larvae was compared by χ2 analysis. ResultsThe detection rate of Wolbachia in adult and larvae of Aedes albopictus were 43.5% （77/177） and 70.4% （190/270）， respectively， with a statistically significant difference （χ2=32.086，P<0.001）， and wAlbA and wAlbB were mainly detected together. The detection rate of Wolbachia in female and male Aedes albopictus were 50.7% （76/150） and 3.7% （1/27）， respectively， with a statistically significant difference（χ2=20.533，P<0.001）. The detection rate of adult Aedes albopictus in Songjiang wild area， residential area and Hongkou residential area were 91.7% （55/60）， 18.8% （22/117） and 41.7% （30/72）， respectively， with a statistically significant difference （χ2=54.322，P<0.001）. Genotyping and phylogenetic analysis showed that adult and larvae of Aedes albopictus infected with Wolbachia were mainly wAlb A and wAlb B. In addition， some sequences formed clades independently， and the genetic distance from other sequences was relatively large. ConclusionInfection of Wolbachia in Aedes albopictus is relatively common in Songjiang District. The main genotypes are wAlb A and wAlb B and there may be other subtypes， which are worthy of further exploration and research.
ABSTRACT
ObjectiveTo develop a new mosquito trap and evaluate its effectiveness in Aedes albopictus monitoring in an urban community. MethodsThe first-round field test was conducted in a well-greened residential neighborhood with high Aedes albopictus density calculated by human landing catch in August 2022， in Minhang District， Shanghai. 65 new test containers with different designs were randomly deployed in the field. These trap containers were designed by different material， color， hole size， shape and top cover colors. The results of mosquito and its egg trapping were observed and recorded continuously for 7 days. In September 2022， the second round of experiment was conducted. After comparison， an optimized trap container was designed. 140 new trap containers were compared with 140 traditional ones to evaluate the effectiveness. SPSS 22.5 software was used for statistical analysis. ResultsThere were significant changes in the outcome of mosquito and its egg trapping on the 4th and 7th day of the pre-experiment deployment of the three kinds of containers. The 200 ml container cup with three round holes in the body had the best effect on trapping mosquitos and eggs， with a positive rate of 45.5% （5/11）， while other type of contrainer cup only had a positive rate of 12% （6/50） in trapping mosquitos and eggs. Statistical significant differences （χ2=45.443，P <0.001） existed between the two tpyes of cups within the first kind of trapping container. The second kind of trapping container showed round and oval holes had better effect on mosquito trapping， with a positive rate of 55.6% （5/9）. The third kind of hanging container can resist strong wind. The best mosquito trapping effect of three round holes was 66.7% （2/3）. The container wall should not be made of rough material， which was easy to cause the escape of adult mosquitoes. Combined with the three types of containers， the new contariner should be top transparent， and the top 1/3 of the side should paint black with 3 round holes. The effective recovery rate of the new container was higher than that of the traditional one under the exclusion of human factors， and had the advantage of preventing rain， wind and rollover， but the effect of trapping mosquito and its egg was comparable to the traditional one（χ2D4=0.197，P=0.658； χ2D7=0.125 ，P=0.724）. ConclusionThis new type of mosquito trap is worth further exploration and research， which can improve the trapping efficiency， overall recovery rate and the accurate confirmation of the mosquito density.
ABSTRACT
Zhishi Xiebai Guizhi Tang， derived from Synopsis of the Golden Chamber （《金匮要略》， Han dynasty， ZHANG Zhongjing）， is a famous classical prescription commonly used for chest impediment. By means of bibliometrics， the authors collected 63 ancient Chinese medical books related to Zhishi Xiebai Guizhi Tang and screened 36 effective books for statistical analysis of the historical origin， composition， main indications， dosage， processing， decocting method and other aspects of the prescription. The findings revealed that Zhishi Xiebai Guizhi Tang was composed of five medicinal herbs， namely， Aurantii Fructus Immaturus， Allii Macrostemonis Bulbus， Cinnamomi Ramulus， Magnoliae Officinalis Cortex， and Trichosanthis Fructus， with the function of activating Yang， dissipating mass， dispelling phlegm and lowering Qi. The prescription was mainly used to treat chest impediment， chest fullness， chest pain， wheezing， coughing and shortness of breath caused by suppressed Yang Qi， stagnant heart Qi， stagnant phlegm and stasis， and phlegm evil blocking heart， chest or lungs. Additionally， it was found that there were 70 modern literature recording the clinical applications of Zhishi Xiebai Guizhi Tang， and the main system diseases treated were circulatory system （51， 72.85%）， endocrine system （4， 5.7%）， respiratory system （9， 12.85%） and digestive system （6， 8.57%）， of which circulatory system is dominated by coronary heart disease （chest impediment in traditional Chinese medicine）. The involved medical syndrome types mainly included internal obstruction of phlegm heat and turbidity， obstruction of phlegm turbidity and stasis， congealing cold， phlegm， stasis and Qi stagnation， chest Yang depression and combined phlegm and stasis. Ancient medical records and modern clinical application are the keys to ensure the safety and effectiveness of famous classical prescriptions and compound preparations. Therefore， this paper sorted and mined ancient medical books of Zhishi Xiebai Guizhi Tang and statistically analyzed its modern clinical application， aiming to provide a literature reference for the research and development of new drugs and clinical application of the prescription.
ABSTRACT
ObjectiveTo investigate the resistance to beta-cypermethrin in Aedes albopictus in Xuhui District， Shanghai， China， and determine the effects of insecticide components， concentration and distance on eliminating resistant population of Aedes albopictus in ultra-low volume （ULV） spray， which would provide scientific evidence for effective mosquito control strategy and rational use of beta-cypermethrin. MethodsLarval impregnation method recommended by the World Health Organization was used to determine the drug resistance in Aedes albopictus larvae to calculate the median lethal concentration （LC50） of insecticides to Aedes albopictus larvae. The resistance to insecticides in female adults of Aedes albopictus was measured by the adult mosquito contact tube method recommended by the World Health Organization， and the 24-hour mortality （%） of female mosquitoes caused by insecticides was measured. Then the 24-hour mortality （%） of resistant female adults of Aedes albopictus due to beta cypermethrin monotherapy and compound agents was calculated by ULV spray. ResultIn 2016， 2017， 2019 and 2021， the resistance ratio in Aedes albopictus larvae to beta-cypermethrin was 9.22， 68.22， 37.33 and 59.22， respectively. In 2021， the 24-hour mortality of Aedes albopictus female adults was 62.07%. ULV sprayer experiments were performed using 4.5% beta-cypermethrin （single dose） and 12.0% beta-cypermethrin-chlorpyrifos （compound dose）. The 24-hour mortality increased with the concentration of the insecticides. The overall mortality caused by compound was higher than that by single dose. The mortality were 24.24%， 31.60% and 97.83% at the concentrations of 0.045 0%， 0.067 5% and 0.090 0% for single dose， respectively， and 58.87%， 61.62% and 90.00% at the concentrations of 0.12%， 0.18% and 0.24% for compound dose， respectively. There was no significant difference in mortality when spraying distance was 10 m， 30 m and 50 m. ConclusionAedes albopictus in Xuhui District is developed varying resistance to beta-cypermethrin. It warrants to strengthen the monitoring on insecticide resistance to formulate scientific and reasonable strategy for insecticide use. and reduce the resistance level of the Aedes albopictus to beta-cypermethrin. Compound dose is recommended to improve the effect. In addition， comprehensive treatment may be adopted to reduce the resistance.
ABSTRACT
Objective To investigate the type and consumption of sanitary insecticides used in Putuo District of Shanghai， determine the current resistance of Aedes albopictus to the insecticides， and explore the causes of regional variations in insecticide resistance spectrum. Methods Public and private institutions of pest control operation were investigated on the use of sanitary insecticides. Dipping method and tube method were used to measure the insecticide resistance of Aedes albopictus， including larvae and adults. Results The main insecticides used in residential areas and governmental units was β-cypermethrin， while that in markets and public environment was propoxur. In addition， and the insecticides in dengue control program was λ-cyhalothrin. Aedes albopictus larvae had medium resistance to parathion， and were sensitive to propoxur， with insignificant change within three years. Their resistance to permethrin and deltamethrin was medium and high， respectively. Moreover， resistance to β-cypermethrin increased over years. In contrast， resistance of adult Aedes albopictus differed by area， except consistently being sensitive to fenitrothion. Conclusion Multiple sanitary insecticides have been used in Putuo District. In addition， Aedes albopictus has different resistance to these insecticides by area. It suggests that resistance surveillance should be promoted， which may be crucial for scientific application of insecticides and impede the development of potential resistance.

The mosquitos kept a high resistance to permethrin， and the resistance ratios were 54.00， 140.00， 52.00 respectively， in 2015， 2017， 2019. Besides， A. albopictus also kept a medium resistance to propoxur， and the resistance ratios were 15.34， 13.06， 10.83 respectively， in 2015， 2017， 2019. To deltamethrin， A. albopictus showed high resistance in 2015 and medium resistance in 2017， the resistance ratios were 40.00 and 35.00. To temephos， A. albopictus showed low resistance in 2015， with the resistance ratio of 9.38. Conclusion A. albopictus has developed high resistance to permethrin in Yangpu District of Shanghai， and cautious and reduced use of permethrin is suggested. It is necessary to implement and adopt the strategy of comprehensive management， in order to establish the long-term mechanism for mosquito control and prevention.
ABSTRACT
Objective To determine the seasonal fluctuation and population distribution of Aedes albopictus in Jiading District， and provide scientific evidence for the prevention and control of dengue fever and other Aedes-borne diseases. Methods In 2020， the mosq-ovitrap method and mosq-ovitrap index （MOI） were used to monitor and evaluate the density of Aedes albopictus in Jiading District. Spatial and temporal distribution of Aedes albopictus was determined. Chi-square test was used for statistical analysis. Results In 2020， the annual average MOI was determined to be 4.10， which was under safety threshold. The seasonal fluctuations showed a unimodal distribution， which peaked in July. The fluctuation trend in urban area was similar to the overall trend， while that in the non-urban area showed a bimodal distribution with peaks in June and August. The density of Aedes albopictus at different monitoring sites varied widely，with the highest MOI （6.64） at Anting town and the lowest MOI （2.09） at Huating town. The distribution of Aedes albopictus in different habitats also varied widely； the highest density was observed in environments as waste collection stations and construction sites， with the highest MOI 33.33 in waste collection stations in peak season. The MOI value of Aedes albopictus in residential areas was significantly higher than that in non-residential areas （χ2 = 6.082， P = 0.014）. Conclusion Aedes albopictus is quite common in Jiading District. In certain areas， Aedes density may exceed the safety threshold from May to September. More targeted mosquito control measures should be implemented in waste collection stations， construction sites and residential areas.
ABSTRACT
Objective Based on mosq-ovitrap monitoring method of Aedes albopictus， to determine the spatial and temporal distribution of Aedes albopictus in Songjiang District and provide scientific evidence for prevention and control of mosquito-borne diseases. Methods From May to October， 2018‒2020， density of Aedes albopictus was monitored by using the mosq-ovitrap method. Sub-districts and towns were used as the monitoring units and the difference in mosquito ovitrap index （MOI） was compared by seasons， years and habitats. Results The total number of positive mosquito ovitraps was 1049 in 2018‒2020， and the average MOI was 8.10. Four sub-districts/towns in the urban area and the northern area had the relatively high MOIs. Moreover， MOIs in residential and external environments were higher than other habitats. In addition， MOI of Aedes albopictus decreased over years from 2018 to 2020. Conclusion Aedes albopictus is widely distributed in Songjiang District. Although the number of mosquito decreased over years after the implementation of mosquito control measures， reproduction of mosquito remains excessive in some areas and seasons. It is necessary to perform targeted control measures based on comprehensive monitoring methods.

ABSTRACT
Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.
ABSTRACT
Alzheimer's disease (AD) is a degenerative neurological disease with unclear pathogenesis. The disease progress/trajectory of AD patients can be adequately described by establishing quantitative pharmacological disease progression model. Integrating biomarker information into the model can provide more insight to understand the potential pathological mechanisms and facilitate the optimization of future trial design. Several empirical and semi-mechanism disease progression models have been published. This mini-review is expected to offer some references for the further AD clinical research and new drug development.
ABSTRACT
Objective:To investigate and analyze the epidemiological and clinical characteristics of 46 patients with corona virus disease 2019 (COVID-19) in Beijing City.Methods:A retrospective study was conducted to analyze the data of 46 patients with COVID-19 in Beijing from 20th January 2020 to 8th February 2020 at the Fifth Medical Center of the PLA General Hospital in Beijing City. Twelve, 23 and 11 patients were assigned to the mild group, common group and severe group, respectively. The epidemiological history, clinical characteristics, laboratory tests and imaging inspections were analyzed. Statistical analysis used Fisher exact test. If P<0.05, post- hoc test was used for pairwise comparison, and the statistics were corrected by Bonferroni test. Results:Among the 46 patients included in this study, 27 were male and 19 were female. The age range was between 3-79 years old, and the age was (41.8±16.3) years old. The average incubation period was (4.85±3.00) days. A total of 26 cases (56.5%) were clustered patients, and 26 cases had a history of staying in Wuhan, 10 cases had contact with Wuhan personnel. Fever (39 cases, 84.8%), cough (27 cases, 58.7%), and fatigue (25 cases, 54.3%) were the main clinical symptoms for these patients. The decrease in white blood cell counts occurred in 12 patients, four had the decrease in T lymphocyte percentage, 17 had the decrease in CD4 + T lymphocyte counts, seven had the decrease in CD8 + T lymphocyte counts, 21 had the increase level of C reactive protein (45.7%), and interleukin-6 (IL-6) level increased in 32 cases (69.6%), erythrocyte sedimentation rate (ESR) increased in 23 cases (50.0%), serum ferritin level increased in 26 cases (56.5%), and blood lactic acid level increased in nine cases. There were statistically significant differences in the proportion of cases with decreased absolute value of CD8 + T lymphocytes and T lymphocytes counts among the mild, common and severe groups (all P<0.05). Comparing the proportion of cases in the three groups with elevated C reactive protein, IL-6, ESR, serum ferritin and blood lactic acid levels, the differences were statistically significant (all P<0.05). The proportion of cases with elevated C reactive protein levels in severe group was higher than those in mild and common groups. The proportion of cases with elevated IL-6, ESR, and serum ferritin levels in severe and common group were higher than those in mild group. The proportion of cases with elevated blood lactic acid levels in severe group was higher than those in mild group. The differences between the above groups were statistically significant (all adjusted P<0.017). Analysis of chest X-rays results showed that 34 patients (73.9%) had inflammation in the lungs. Conclusions:The epidemiological characteristics of patients with COVID-19 in Beijing City are mainly imported cases and clustered cases. The clinical manifestations are mainly fever, fatigue and cough. C reactive protein, IL-6, ESR, serum ferritin and blood lactic acid levels are higher in severe patients.

ABSTRACT
Objective To explore the relationship of quality of life with optimisms and sense of coherence in adult kidney transplant recipients. Method A total of 295 kidney transplant recipients participated in the study by a self-designed general questionnaire, revised life orientation test (LOT-R), sense of coherence (SOC-13) and the MOS 36-item short form health survey (MOS SF-36). Results The mean score of mental health scale (PCS) was 47.02±7.30, which differed with different age, employment status and transplant vintage (P ＜0.01). The mean score of phyical health scale (MCS) was 46.87 ±11.14, which differed with education, economic burden and transplant vintage (P ＜0.05). PCS and MCS were positively correlated with the total score of sense of coherence (52.05％) and optimism (23.45％) (P＜0.001). Optimism played a partially mediating role in the relationship between sense of coherence and quality of life. Conclusions The quality of life of kidney transplant recipients needs to be improved, which was at a low level.Optimism (medium to high level) and sense of coherence (medium to low level) are influencing factors of the quality of life. Improving accessment of mental state of patients with kidney transplant receients, paying more atentent and support to their mental change can improve their optimism and sense of coheherce and then life quiality.
ABSTRACT
Objective To analyze the risk factors of failure of emergency treatment with invasive mechanical ventilation (IPPV) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods The clinical data of 122 patients with AECOPD to undergo IPPV admitted to the Emergency Center of Kaifeng Central Hospital from July 2015 to March 2018 were retrospectively analyzed. The patient's general information [gender, age, body mass index (BMI)] and the patient's body temperature (T) at initial IPPV, respiratory rate (RR), mean arterial pressure (MAP), heart rate (HR), white blood cell count (WBC), hemoglobin (Hb), electrolyte (K+, Na+ and Cl-), pH value, D-dimer, albumin, C-reactive protein (CRP), blood lactic acid (Lac), B-type brain natriuretic peptide (BNP), procalcitonin (PCT), serum creatinine (SCr), oxygenation index, respiratory index (RI), the occurrence of serious arrhythmia or not, Glasgow coma score (GCS) were statistically analyzed. The indicators with statistical significance in the univariate analysis were introduced into the multivariate Logistic regression analysis to screen out the risk factors affecting the failure of IPPV in the patients; receiver operating characteristic (ROC) curve was drawn to analyze the test effectiveness of the risk factors. Results There were totally 98 cases underwent emergency IPPV, failure in 17 cases and success in 81 cases. The levels of oxygenation index, pH value, WBC and GCS scores of the IPPV success group were significantly higher than those of the IPPV failure group [oxygenation index (mmHg, 1 mmHg =0.133 kPa): 304.10±115.35 vs. 285.93±184.64, pH value: 7.34±0.17 vs. 7.18±0.24, WBC (×109/L): 40.90±8.72 vs. 26.61±6.86, GCS score: 12.42±1.35 vs. 9.89±2.13, all P < 0.05]; the levels of RI, D-dimer, PCT, Lac and incidence of serious arrhythmia in the IPPV success group were significantly lower than those in the IPPV failure group [RI: 2.53±2.39 vs. 3.69±3.64, D-dimer (mg/L): 1.80±0.06 vs. 3.16±2.60, PCT (μg/L): 1.36±0.65 vs. 2.23±2.07, Lac (mmol/L): 3.98±0.63 vs. 7.06±3.44, incidence of serious arrhythmia: 23.46% (19/81) vs. 47.06% (8/17), all P < 0.05]. Logistic regression analysis showed that RI [odds ratio (OR) = 3.479, 95% confidence interval (95%CI)= 1.248-11.996], pH value (OR = 3.153, 95%CI = 1.256-8.656), WBC (OR = 3.364, 95%CI = 1.171-11.561), and the occurrence of severe arrhythmia (OR = 4.125, 95%CI = 0.042-0.342) were risk factors affecting the prognosis of AECOPD patients treated with IPPV (all P < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) of RI, pH value, WBC and occurrence of severe arrhthmia was 0.718 (P = 0.012), 0.832 (P = 0.008), 0.645 (P = 0.004), 0.617 (P = 0.003), and the sensitivity were 37.0%, 55.6%, 81.5%, 60.4%, the specificity were 19.1%, 26.8%, 60.3%, 83.0% respectively, that had certain value to predict the failure of using IPPV to treat patients with AECOPD. Conclusion Multiple factors may result in failure in emergency patients with AECOPD to apply invasive mechanical ventilator for treatment, that may lead to death, and RI, pH value, WBC, the occurrence of severe arrhythmia are the independent risk factors of failure in such patients using IPPV; emergency physicians should pay attention to AECOPD patients' risk factors at initial period of using IPPV in order to give early warning after assessment.
ABSTRACT
Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.
ABSTRACT
Objective To study the association between morning surge (MS) of systolic blood pressure (SBP) and white matter lesions in elderly essential hypertensive (EH) patients.Methods Three hundred and thirty-seven elderly EH patients from Zhangqiu of Shandong Province were divided into MS group (n=150) and non-MS group (n=187).Their 24 h ambulatory SBP was monitored.Their white matter hyperintensity (WMH) was assessed according to their brain MRI.Results The total WMH,periventricular WMH,and deep WMH were significantly higher in MS group than in non-MS group (P＜0.01).The MS of SBP was positively related with the total WMH,periventricular WMH,and deep WMH (r=0.561,r=0.563,r=0.283,P＜0.01),and was an independent risk factor for total WMH,periventricular WMH,and deep WMH after adjustment for confunders (r=0.479,r=0.486,r=0.208,P＜0.01).Conclusion MS of SBP is an independently risk factor for WMH in elderly EH patients.
ABSTRACT
Objective To study the effect of telmisartan combined with rosuvastatin on white matter lesion (WML) in elderly hypertensive patients.Metheds Three hundred and twenty-nine elderly patients with mild-moderate essential hypertension (EH) were divided into control group (n=167) and combined treatment group (n=162).The patients in control group were treated with telmisartan (40 mg/d) and those in combined treatment group were treated with telmisartan plus rosuvastatin (10 mg/d).Their white matter hyperintensivity (WMH),periventricular white matter hyperintensity (PWMH),and deep white matter hyperintensity (DWMH) were measured by head MRI.Results The total WMH,PWMH and DWMH were significantly higher in two groups in the third and fifth years than at the baseline (P＜0.05).The growth rate of total WMH,PWMH and DWMH was significantly lower in combined treatment group than in control group in the third and fifth years (P＜0.05).Conclusion Telmisartan combined with rosuvastatin plays an important role in stablizing blood pressure,regulating blood lipids,and delaying WML.
ABSTRACT
Purpose To investigate the relationship between HPV infection and p53,p16,EGFR expression and prognosis in patients with salivary adenoid cystic carcinoma (ACC).Methods Totally 76 cases of adenoid cystic carcinoma specimens were selected,PCR-reverse dot blot hybridization was used to detect infection of HPV and SP immunohistochemical method was adopted to detect the expression of p53,p16,EGFR,Cdc2 in tumor tissues.Clinical data were collected and all the patients were followed up.The Kaplan-Meier method was used to estimate median overall survival and the Log-rank test to compare survival curves.Cox regression model was used for multivariate analyses.Results Infection rate of HPV in adenoid cystic carcinoma tissues was 0(0/76).The expression rate of p53,p16,EGFR,Cdc2 protein in adenoid cystic carcinoma tissues were 76.3％ (58/76),57.9％ (44/76),60.5％ (46/76) and 64.5％ (49/76)respectively.There was no correlation of the expression of p53,p16,EGFR and Cdc2 with gender,age,tumor location,TNM stage and histological type of patient.Kaplan-Meier survival analysis showed that EGFR-positive patients had shorter median overall survival rate (OS) than the negative ones (x2 =19.111,P ＜ 0.001).EGFR-positive patients had shorter median progression-free survival rate (PFS)than the negative ones (x2 =6.621,P ＜ O.01).Cdc2 positive patients had shorter median OS than the negative ones (x2 =3.870,P ＜ 0.05).Cdc2 positive patients had shorter median PFS than the negative ones (x2 =6.755,P ＜0.01).Cox regression analysis showed that expression of EGFR and Cdc2 was independent risk factors for the prognosis of patients with salivary gland ACC (relativerisk=13.417,13.075,P＜0.001).Conclusion There is no HPV infection detected in adenoid cystic carcinoma tissues.p53,p16,EGFR and Cdc2 are positively expressed in most salivary adenoid cystic carcinoma,p16 is unsuitable as a surrogate for HPV infection status of patient with ACC.Expression of EGFR and Cdc2 is independent risk factors in the prognosis of patients with salivary gland ACC.For the EGFR or Cdc2 positive patients should be followed up closely.
