ABSTRACT

Objective:To explore the value of color Doppler ultrasound scanner in screening peripheral artery atherosclerosis(AS)of undergraduates on campus.Methods:From June 2020 to June 2022,a total of 300 college student volunteers were selected from Sichuan University of Arts and Sciences and Dazhou Vocational and Technical College,and they were divided into peripheral AS group(59 cases)and healthy control group(241 cases)according to the occurrence of peripheral AS.The general data and blood flow parameters of the two groups were compared,and the risk factors of peripheral AS of undergraduates on campus were further analyzed.Results:The differences of the gender,hyperglycemia rate,hypertension rate,smoking history rate,triglycerides(TG),total cholesterol(TC)and high-density lipoprotein cholesterol(HDL-C)between the AS group and the healthy control group were not statistically significant(P>0.05).The differences of age,obesity rate,hyperlipidemia rate and low-density lipoprotein cholesterol(LDL-C)between AS group and healthy control group were statistically significant(t=6.666,x2=4.256,5.292,t=4.515,P<0.05),respectively.The maximum blood flow velocity(Vmax)and minimum blood flow velocity(Vmin)of the AS group were lower than those of the healthy control group,with statistically significant differences(t=-3.753,-3.905,P<0.05).The resistance index(RI)of the AS group was higher than that of the healthy control group,with statistically significant differences(t=3.126,P<0.05).The dependent variable of the AS group was assigned a value of 1,and the healthy control group was assigned a value of 0.The factors with P<0.05 in univariate analysis were used as independent variables.The multiple factor binary logistic analysis showed that age and high LDL-C were risk factors for peripheral AS(OR=1.664,1.192,P<0.05),while high Vmax and high Vmin were protective factors for peripheral AS(OR=-0.102,-0.170,P<0.05),respectively.Conclusion:The higher the LDL-C level,the lower the Vmax and Vmin,are the higher risks of undergraduates who occur peripheral AS.The LDL-C and ultrasonic blood flow parameters(Vmax and Vmin)can be used to assist the diagnosis about whether occurs peripheral AS.

ABSTRACT

Objective: To explore the feasibility of moving epidemic method (MEM) in the assessment of seasonal influenza (influenza) activity intensity from the perspective of urban agglomeration, assess influenza activity intensity in the Beijing-Tianjin-Hebei region from 2019 to 2021 and evaluate the reliability of surveillance data and the effectiveness of the MEM model application. Methods: The weekly reported incidence rate (IR) of influenza and the percentage of influenza-like illness (ILI%) from 2011-2021 in Beijing-Tianjin-Hebei region were collected to establish MEM models respectively. The model fitting effect and the reliability of the two data were evaluated for the purpose of establishing an optimal model to assess the influenza activity intensity in Beijing-Tianjin-Hebei region from 2019-2021. A cross-validation procedure was used to evaluate the performance of the models by calculating the Youden's index, sensitivity and specificity. Results: The MEM model fitted with weekly ILI% had a higher Youden's index compared with the model fitted with weekly IR at both Beijing-Tianjin-Hebei region level and provincial level. The MEM model based on ILI% showed that the epidemic threshold in Beijing-Tianjin-Hebei region during 2019-2020 was 4.42%, the post-epidemic threshold was 4.66%, with medium, high and very high intensity thresholds as 5.38%, 7.22% and 7.84%, respectively. The influenza season during 2019-2020 had 10 weeks (week 50 of 2019 to week 7 of 2020). The influenza season started in week 50 of 2019, and the intensity fluctuated above and below medium epidemic level for six consecutive weeks. The high intensity was observed in week 4 of 2020, the threshold of very high intensity was excessed in week 5, and the intensity gradually declined and became lower than the threshold at the end of the influenza season in week 8. The epidemic threshold was 4.29% and the post-epidemic threshold was 4.35% during 2020-2021. Influenza activity level never excessed the epidemic threshold throughout the year, and no epidemic period emerged. Conclusions: The MEM model could be applied in the assessment of influenza activity intensity in Beijing-Tianjin-Hebei region, and the use of ILI% to assess influenza activity intensity in this region was more reliable than IR data. Influenza activity intensity in Beijing-Tianjin-Hebei region was higher during 2019-2020 but significantly lower in 2020-2021.

ABSTRACT

Objective: To understand the performance of 2019-nCoV nucleic acid detection in screening of contacts of COVID-19 cases in same flights and provide evidence for the effective screening of persons at high risk for the infection in domestic flights. Methods: The information of passengers who took same domestic flights with COVID-19 cases in China from April 1, 2020 to April 30, 2022 were retrospectively collected,and χ2 test was used to analyze positive nucleic acid detection rates in the passengers in different times before the onsets of the index cases, in different seat rows and in epidemic periods of different 2019-nCoV variants. Results: During the study period, a total of 433 index cases were identified among 23 548 passengers in 370 flights. Subsequently, 72 positive cases of 2019-nCoV nucleic acid were detected in the passengers, in whom 57 were accompanying persons of the index cases. Further analysis of the another 15 passengers who tested positive for the nucleic acid showed that 86.67% of them had onsets or positive detections within 3 days after the diagnosis of the index cases, and the boarding times were all within 4 days before the onsets of the index cases. The positive detection rate in the passengers who seated in first three rows before and after the index cases was 0.15% (95%CI: 0.08%-0.27%), significantly higher than in the passengers in other rows (0.04%, 95%CI: 0.02%-0.10%, P=0.007),and there was no significant difference in the positive detection rate among the passengers in each of the 3 rows before and after the index cases (P=0.577). No significant differences were found in the positive detection rate in the passengers, except the accompanying persons, among the epidemics caused by different 2019-nCoV variants (P=0.565). During the Omicron epidemic period, all the positive detections in the passengers, except the accompanying persons, were within 3 days before the onset of the index cases. Conclusions: The screening test of 2019-nCoV nucleic acid can be conducted in the passengers took the same flights within 4 days before the onsets of the index cases on board. Passengers who seated within 3 rows from the index cases can considered as the close contacts at high risk for 2019-nCoV, for whom screening should be conducted first and special managements are needed. The passengers in other rows can be classified as general risk persons for screening and management.

ABSTRACT

Influenza is an acute respiratory infectious disease caused by influenza virus. Pregnancy is associated with physiologic and immunological changes that may increase the risk for influenza virus infection and influenza-related complications. Influenza vaccination is the most effective way to prevent influenza virus infection. WHO and many countries have classified pregnant women as a priority population for influenza vaccination, however, there are still many challenges for promoting influenza vaccination in pregnant women in China, influenza vaccination coverage in pregnant women remains low and some influenza vaccine package inserts list pregnancy as an absolute contraindication. In this paper, we summarize the research progress in the effects of influenza infection and influenza vaccination during pregnancy both at home and abroad, then discuss the strategies to promote influenza vaccination in pregnancy for the purpose of providing reference for the related research and policy development in China.

ABSTRACT

This article uses the "behavioural and social drivers of vaccination" model released by the World Health Organization (WHO) in 2022 to analyze influenza vaccine policy documents issued by the state and governments. This indicates that the current influenza vaccination policy in China has paid some attention to "publicity and mobilization", but it still pays insufficient attention to "vaccination convenience". It is recommended to continue to strengthen publicity and mobilization, explore ways to improve the convenience of vaccination, formulate corresponding plans to improve the convenience of vaccination, scientifically set vaccination rate targets, and encourage areas with conditions to carry out free vaccination projects for key populations.

ABSTRACT

The COVID-19 pandemic is yet another reminder that the threat of infectious disease has never really gone away. As the cornerstone of preventing and controlling infectious diseases, effective surveillance and early warning are of great significance in understanding the outbreak and epidemic of specific infectious diseases and putting forward effective prevention and control measures. Therefore, we must continue strengthening the construction of infectious disease surveillance and early warning system. We reviewed the surveillance and early warning practices of infectious diseases in major countries and regions, then discussed the development direction in the field of surveillance and early warning of infectious diseases to provide the reference for strengthening the construction and capacity of infectious disease surveillance and early warning system in China.

ABSTRACT

FGF21-164 is a fusion protein obtained by structural modification and coupling of endogenous FGF21. It is a candidate drug used in the treatment of glucose and lipid metabolic disorders caused by obesity. In this study, the candidate peptide mass spectrometry information of the protein hydrolyzed by trypsin was predicted by Skyline software and verified by high resolution mass spectrometry. The specific surrogate peptide (YLYTDDAQQTEAHLEIR) with the best mass response was selected after optimizing ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Under ESI positive ion mode, the parent ion m/z 689.3 with 3 charge and the product ion m/z 738.4 with single charge can be monitored. After dilution by PBS, the serum samples were denatured under 60 ℃ and alkylated to reduce the matrix effect, then incubated with trypsin at 37 ℃ for 2 h, to obtain the surrogate peptide. The chromatographic separation was carried out on an EclipsePlus C18 column (2.1 mm×50 mm, 1.8 μm) using aqueous solution containing 0.1% formic acid (phase A) and acetonitrile solution containing 0.1% formic acid (phase B). Finally, the concentration of FGF21-164 fusion protein in mouse serum was quantitatively analyzed by external standard method by monitoring the above ion pairs using triple quadrupole mass spectrometer. This method showed a good linearity in the range of 2.50-500 μg·mL-1 (r = 0.998 8), and was successfully applied to the pharmacokinetic study of FGF21-164 fusion protein in mice. This experiment was approved by the Experimental Animal Ethics Committee of Shanghai Institute of Materia Medica, Chinese Academy of Sciences (batch number: 20180004040450). Compared with the endogenous FGF21, the t1/2 of FGF21-164 fusion protein was prolonged from 0.5 h to 2.6 h, which is expected to prolong the therapeutic efficacy of this protein.

ABSTRACT

Objective:To study the early effect of arthroscopy in the treatment of obsolete traumatic subscapularis tears.Methods:A retrospective case series study was used to analyze the clinical data of 28 patients with obsolete traumatic subscapularis tears admitted to Second People 's Hospital of Changzhou City from July 2017 to July 2020,including 16 males and 12 females,aged 47-72 years[(60.5±6.3)years]. According to Lafosse classification,the injury size was upper one third tear in 9 patients,upper half tear in 18 and complete tear in 1. According to Patte classification of the degree of retraction,4 patients were with no retraction,7 with retraction to the level of the lesser tuberosity,14 with retraction to the level of the humeral head,and 3 with retraction to the level of the glenoid. According to Goutallier classification,the level of fatty infiltration was at grade 0-1 in 17 patients,at grade 2 in 10 and at grade 3-4 in 1. All patients were repaired by arthroscopic surgery. The wound healing was observed at 2 weeks postoperatively. The visual analogue score(VAS),University of California at Los Angeles(UCLA)shoulder rating score,shoulder active forward elevation(AFE),active external rotation(AER),active internal rotation(AIR)were assessed before operation and at 3 months and 6 months postoperatively. Six months after operation,reexamination of the front and side view of the shoulder and MRI of the shoulder were performed to assess the recovery of the subscapular tendon. Results:All patients were followed up for 6-12 months[(8.7±1.3)months]. All wounds healed 2 weeks after operation,with no infection occurred. The VAS was(3.5±0.7)points and(2.6±0.5)points at 3 months and 6 months postoperatively,lower than(6.3±1.2)points before operation( P<0.01). The UCLA score was(20.4±2.5)points and(25.6±6.2)points at 3 months and 6 months postoperatively,higher than(9.5±1.7)points before operation( P<0.01). The preoperative range of motion of the affected shoulder in AFE,AER and AIR was(80.2±12.6)°,(52.5±7.6)°,(3.7±1.2)°,respectively. Three months after operation,the range of motion was(113.2±7.5)°,(60.1±6.3)°,(6.8±1.6)°,respectively. Six months after operation,the range of motion was(122.3±15.2)°,(65.6±10.5)°,(7.8±2.3)°,respectively. The range of motion of the affected shoulder at 3 months and 6 months postoperativley was better than that before operation( P<0.01). Six months after operation,MRI showed good recovery in 27 patients,while a small re-tear in 1 patient(Goutallier classification grade 3). Conclusion:For patients with obsolete traumatic subscapularis tears,arthroscopic repair can significantly relieve the pain,and recover range of motion and function of the joint.

ABSTRACT

Objective To investigate the correlation between serum adiponectin levels and post-stroke cognitive impairment (PSCI). Methods From January 2018 to December 2018, consecutive patients with ischemic stroke admitted to the Departments of Neurology, the Affiliated Brain Hospital of Guangzhou Medical University, Dongguan Changping Hospital, and Jiangsu Provincial Second Chinese Medicine Hospital were enrolled. Serum adiponectin concentration was detected by radioimmunoassay. The cognitive function assessment was performed 1 month after the onset of stroke using the Montreal Cognitive Assessment (MoCA). The total score of MoCA <22 was defined as PSCI. Univariate analysis was used to compare the baseline data between groups, and multivariate logistic regression analysis was used to determine the association between serum adiponectin levels and PSCI. Results A total of 257 patients with acute ischemic stroke were enrolled, with age 66.5 ± 9.9 years, 139 (54.1% ) males, and 91 (35.4% ) with PSCI. Age (68.2 ± 8.1 years vs. 65.6 ± 10.8 years; t=2.007, P=0.046 ), homocysteine (16.0 ± 6.2 μmol/L vs. 14.5 ± 4.5 μmol/L; t= 2.208, P= 0.028 ), and high-sensitivity C-reactive protein ( 7.0 [3.3-9.9] mg/L vs. 4.7 [2.2-9.6] mg/L; Z=2.346, P=0.019 ) as well as the proportion of hypertension (64.8% vs. 50.6% ; χ2 =4.824, P=0.028), diabetes (33.0% vs. 21.1% ; χ2 =4.392, P=0.036), leuko-araiosis (47.2% vs. 32.5% ; χ2 =5.422, P=0.020) and diffusion weighting imaging-Alberta Stroke Project early CT score 0-7 (59.3% vs. 41.4% ; χ2 =6.942, P=0.008) in the PSCI group was significantly higher than that of the non-PSCI group, while the adiponectin level was significantly lower than that of the non-PS-CI group (5.4 [3.5-8.4] mg/L vs. 7.0 [5.3-9.3] mg/L; Z=3.624, P=0.001 ). Multivariate logistic regression analysis showed that after adjusting for the confounding factors, the lower serum adiponectin level was an independent risk factors for PSCI (the 1st quartile group vs. the 4th quartile group: odds ratio 2.152, 95% confidence interval 1.119-5.039; P=0.047). Conclusions Low serum adiponectin level might be an independent risk factor for PSCI in patients with ischemic stroke.

ABSTRACT

OBJECTIVE@#Apios americana, a plant used as a staple ingredient of native American diets, has various properties, including anti-cancer, anti-hyperglycemic, hypotensive, and anti-inflammatory activity. In Japan, Apios is used as a post-natal medication. After parturition, women undergo a period of recovery as they return to pre-pregnancy conditions. However, few health products that aid post-partum recovery are on the market. We explored whether Apios can accelerate the post-partum recovery process, in particular the involution of the uterus.@*METHODS@#Female rats kept in individual cages were mated with two male rats, with the exception of the control group (female rats without mating, on basal diet; n=6). After delivery, rats were divided into five groups based on their diet: basal diet (model; n=6); basal diet+oral intake at 5.4 g/kg of Chanfukang granules (a Chinese patent medicine preparation for post-partum lochia) (positive; n=6); basal diet containing 10% Apios powder (low; n=6); basal diet containing 20% Apios powder (medium; n=6); basal diet containing 40% Apios powder (high; n=6). Five days later, uteri and spleens were weighed. Uterus and spleen indices for each rat were calculated by dividing visceral weight by the total weight. Hormone and cytokine concentrations were measured using enzyme-linked immunosorbent assay (ELISA). Histological analysis of uteri was completed using hematoxylin and eosin (H&E) staining. Expression of matrix metalloproteinases and inhibitors in uteri was measured by western blotting.@*RESULTS@#Our results showed that Apios treatment reduced the post-partum uterus index and regulated the hormone concentrations. Moreover, we found that the process of uterine involution was accelerated, based on morphological changes in the uterus. In addition, our results indicated that Apios alleviated the inflammatory response induced by the involution process. Transforming growth factor β was also found to be regulated by Apios. There were significant downregulation of matrix metalloproteinases and upregulation of their inhibitors by Apios, which suggested that Apios increased the rate of the collagen clearance process.@*CONCLUSIONS@#These results, based on experimental observations at the molecular and protein levels, verified our hypothesis that Apios can improve uterine involution, and demonstrated the potential application of Apios in post-partum care.

ABSTRACT

OBJECTIVE@#To study the effect of soothing liver, relieving depression, invigorating spleen and reinforcing blood on reducing delirium in elderly patients with hip fracture.@*METHODS@#From December 2014 to June 2018, 180 elderly patients with hip fracture admitted were divided into treatment group and placebo group according to the order of admission:90 patients in treatment group were treated with Jiawei Xiaoyao Powder(JWXYP), including 32 males and 58 females, with an average age of(72.12±4.92), involving 67 cases of femoral trochanter fractures and 23 cases of femoral neck fractures; 35 cases underwent dynamic hip screw fixation, 31 cases underwent intramedullary fixation and 24 cases underwent artificial hip replacement. In the placebo group, 90 patients were treated with placebo, including 37 males and 53 females, with an average age of(72.91±5.43) years old, involving 69 cases of femoral trochanteric fractures and 21 cases of femoral neck fractures, including 37 cases underwent dynamic hip screw fixation, 30 cases underwent intramedullary fixation and 23 cases underwent artificial hip replacement. The age, sex, injury site, intraoperative bleeding volume, postoperative drainage, operation time, anesthesia time, post-operative pain score, post-operative hemoglobin, post-operative CRP, delirium severity(DRS) score and delirium occurrence were observed and compared between the two groups.@*RESULTS@#All patients were followed up until delirium returned to normal, postoperative delirium was found in 12 cases (13.33%) in the treatment group and in 39 cases(43.33%) in the placebo group, the treatment group was significantly better than the placebo group. The monitoring indexes of the two groups were compared:post-operative pain score(=0.002), post-operative hemoglobin(=0.012), post-operative CRP(=0.042).@*CONCLUSIONS@#JWXYP can relieve liver depression, invigorate spleen and invigorate blood circulation, reduce pain, inflammatory stimulation and supplement blood volume after operation, and significantly reduce the incidence of delirium after operation.

ABSTRACT

Objective: To study the efficacy, safety and long-term outcomes of integrated strategy of bortezomib-based induction regimens followed by autologous hematopoietic stem cell (ASCT) and maintenance therapy in Chinese multiple myeloma (MM) patients. Methods: 200 MM patients receiving integrated strategy of bortezomib--based induction regimens followed by ASCT and maintenance therapy were retrospectively and prospectively analyzed from December 1. 2006 to April 30. 2018. Results: The complete remission rates (CR) and better than very good partial remission rates (VGPR) after induction therapy, transplantation and maintenance therapy were respectively 31% and 75.5%, 51.8% and 87.7%,73.6% and 93.4%. There was no difference between 4 cycles and more than 5 cycles induction chemotherapy. The negative rate of MRD detection by flow cytometry was 17.6% and 38.2% respectively after induction and 3 months after transplantation. The negative rate of MRD gradually increased during the maintenance therapy. The success rate of high dose CTX combined with G-CSF mobilization was 95.5% and transplantation related mortality (TRM) was zero. The median time to progress (TTP) was 75.3 months and the median overall survival (OS) was 99.5 months. TTP of patients obtaining CR and negative MRD after induction were longer that those of no CR and positive MRD. TTP and OS of patients receiving triple-drug induction and ASCT in early stage were longer than those of double-drug induction and ASCT in late stage. LDH≥240 U/L, high risk cytogenetics, ISS II+III stage and HBsAg positive were prognostic factors at diagnosis. However, only MRD and high risk cytogenetics were independent prognostic factors after transplantation and maintenance therapy. The clinical characteristics of patients of TTP ≥6 years were listed below: light-chain type M protein, ISS I stage, normal level of hemoglobin and platelet, normal LDH, HBsAg negative, chromosome 17p-negative, good response and sustained good response. Conclusions: Integrated strategy of bortezomib-based induction regimens followed by ASCT and maintenance therapy can significantly improve the short-term and long-term efficacy. The prognostic factors of TTP in different disease stages were different. Response to treatment, especially MRD, played a more important role in prognostic factors.
