Objective To analyze the epidemiological and etiological characteristics of hand,foot and mouth disease(HFMD)in Honghe Prefecture,Yunnan Province from 2013 to 2021,and provide basis for the development of prevention and control strategies for HFMD. Methods The case data of HFMD in Honghe Prefecture,Yunnan Province from 2013 to2021 were extracted from the“China Disease Prevention and Control Information System”. Descriptive epidemiological analysis method was used to analyze the incidence rate,severe rate,mortality rate. The nucleic acids of enterovirus-A71(EV-A71)and Coxsackievirus-A16(CV-A16)were detected by Real-time PCR in throat swabs,anal swabs or stool samples from 16 586 cases of HFMD,and the etiological characteristics were analyzed. Results A total of 78 356 cases of HFMD were reported from 2013 to 2021 in Honghe Prefecture,Yunnan Province,with 354 severe cases and 11 deaths. The average annual incidence rate of HFMD was 187. 47/100 000,with an upward trend from 2013 to 2015,and reached the first peak in 2015,which showed a downward trend from 2016 to 2017,while increased,reached the second peak,and then gradually decreased and tended to be flat in 2018. The severe and death rates have been declining since 2015. The age group of 0～7 years old showed high incidence,which accounted for 97. 85%(76 670/78 356)of the total incidence,and the average annual incidence of 1～2 years old group was the highest(4 397. 98/100 000). Generally,the time distribution showed a bimodal distribution,which were from April to July(summer peak)and from October to December(autumn peak),and the peak in summer was higher than that in autumn. The number of cases and severe cases in males were significantly higher than those in females（χ~2= 1 154. 436 and 5. 183,respectively,each P < 0. 05）. The average annual incidence and severe rate in the northern part of Honghe Prefecture were significantly higher than those in the southern part（χ~2= 18 573. 742 and 11. 036,respectively,each P < 0. 05）. Among 16 586 HFMD cases,EV-A71,CV-A16 and other enteroviruses accounted for 18. 71%,20. 38% and 60. 91% of cases,respectively,with significant difference（χ~2= 5 426. 965,P < 0. 05）. The dominant pathogen was EV-A71 in 2013 and 2015,while CV-A16 in 2014,and other enteroviruses became the dominant pathogens in 2016 — 2021. Conclusion The epidemic trend of HFMD in Honghe Prefecture,Yunnan Province from 2013 to 2021 was seasonal and regional,with children under the age of 7 being the key population,and other enteroviruses have become the dominant pathogens after 2016. HFMD prevention and control knowledge publicity should be strengthened,good hygiene habits should be advocated,and parents' awareness of disease prevention should be raised. EV-A71 vaccination should be strengthened to reduce EV-A71 infection and effectively prevent severe cases and deaths.

Objective To study the effect of chronic electrical stimulus at a low physiological frequency on the expression of myosin heavy chain (MHC) in genioglossus of rabbits with chronic hypoxia.Methods Twenty-four adult rabbits,weighing 2.3?0.1kg,were randomized into control group (A),chronic hypoxia group (B),10 Hz electrical stimulus group (C),and 10+40 Hz electrical stimulus group (D).Rabbits in groups C and D received electrical stimulus of genioglossus at a frequency of 10 Hz and 10+40 Hz,respectively,while those in group B received no electrical stimulus,after they were placed in a hypobaric hypoxia cabin,8 h a day for 5 weeks,with free access to food and water.Expression of MHC in genioglossus of rabbits in the 4 groups was detected by SDS-PAGE and semi-quantitative inverse transcription RT-PCR,respectively.Results The expression level of MHCⅠand MHCⅠmRNA was significantly lower while that of MHCⅡa was significantly higher in group B than in group A [(0.69?0.07)% vs (17.48?4.00)%,(0.69?0.07)% vs (1.05?0.06)%,and (79.89?5.09)% vs (73.33?4.17)%,P

Objective:To evaluate our self-made distraction reductor used in the percutaneous minimally invasive treatment of calcaneal fractures.Methods:A retrospective study was conducted of the 32 patients (37 feet) who had been treated at Department of Orthopaedics, The First Affiliated Hospital to Chongqing Medical University from January 2017 to December 2019 for calcaneal fractures. They were 26 males and 6 females, aged from 20 to 67 years (average, 46.5 years). The height and length of the calcaneus were restored by our self-made tri-plane distraction reductor in all patients; the displaced fracture blocks were reset in a minimally invasive manner in patients with intra-articular fracture; final fixation was performed with a minimally invasive plate and screws. Time for reductor installation, operation time and intraoperative blood loss were recorded; complications, fracture union and reduction were observed; height, length and width of the calcaneus, ankle-hindfoot scores of American Society of Foot and Ankle Surgery (AOFAS), Maryland scores, and visual analogue scale (VAS) were recorded at the last follow-up; B?hler and Gissane angles were compared between pre- and post-operation.Results:All patients were followed up for 12 to 36 months (average, 17.2 months). Time for reductor installation averaged 5.0 min (from 3 to 8 min), operation time 91.5 min(from 70 to 110 min), and intraoperative blood loss 25.2 mL (15 to 50 mL). Superficial infection of traction track occurred in one patient and sural nerve injury in one patient. All fractures united without any reduction loss by the last follow-up. On average, the last follow-up observed a calcaneal height of 39.3 mm, a calcaneal length of 70.6 mm, a calcaneal width of 32.7 mm, an AOFAS score of 87.8, a Maryland score of 86.7 and a VAS score of 2.2. The calcaneal B?hler angle was recovered significantly from 3.7°±13.7° preoperatively to 25.8°±6.4° at the last follow-up, and the calcaneal Gissane angle from 112.2°±21.3° preoperatively to 125.8°±5.7° at the last follow-up ( P< 0.05). Conclusion:In percutaneous minimally invasive treatment of calcaneal fractures, application of our self-made tri-plane distraction reductor can lead to fine clinical efficacy.

With homology cloning approaches coupling with RACE (rapid-amplification of cDNA ends) techniques, the full-length coding sequence of pathogenesis-related protein PR10-1 with differential expression was cloned from the total RNA of the root of Panax notoginseng, and its function was explored furtherly. As a result, the longest 465 bp ORF (named as PnPR10-1 with the Accession No. KJ741402 in GenBank) was detected from the cloned sequence with full-length of cDNA of 863 bp. The corresponding peptide encoded consisted of 155 amino acids, contained some domains such as Bet-v-I, and showed high similarity with that from Panax ginseng by analysis of phylogenetic trees created from the alignments. Real-time quantitative PCR showed that the expression of PnPR10-1 gene was constitutive in different tissues of 1-3 year old plant, suggesting that it might be involved in growth, development, and secondary metabolism; yet it was up-regulated significantly with the infection of Fusarium oxysporum in root, suggesting that it might be involved in defense against many diseases including root rot in P. notoginseng.

The development of the imaging technology enables diagnostic methods of detect intracranial aneurysms diversified. In recent years, the diagnosis of aneurysms was confirmed by digital subtraction angiography (DSA) which was regarded as the "gold standards". However, CT angiography (CTA), which appears as a fast, non-invasive, and easily achievable examination, is becoming as a new option in clinic. With the development of the CT facility and upgrade of the workstation software, CTA is more widely used in both diagnosing and treating intracranial aneurysm. This article reviews the sensitivity and specificity of CTA in the detection of intracranial aneurysms, and systematically analyzes its advantages and disadvantages as well as its development, imaging methods.
