In recent years, the rapid growth of the number of private cars has greatly increased the traffc pressure, so the quality of roads and bridges should be further improved. The paper expounds the related matters of road and bridge engineering from three aspects. Firstly, it expounds the construction principles of road and bridge engineering, which are regarded as the theoretical basis of follow-up research. Secondly, it analyzes the common diseases of road and bridge engineering, including bridgehead damage, reinforcement corrosion, and subgrade uneven settlement, etc. Finally, it puts forward the construction treatment technology of road and bridge engineering on the basis of the construction principles and taking the common diseases as reference.

Soft Soil Foundation

Municipal road and bridge engineering is an important part of the transportation road construction in the city. Its construction quality directly affects the transportation quality and driving safety of the whole municipal road traffic. Among them, the foundation engineering of municipal road and bridge engineering is the main construction link. In the current municipal road and bridge construction process, it is often affected by many factors, leading to the reduction of the construction quality of municipal road and bridge engineering, especially the construction treatment of soft soil foundation in the foundation engineering, which is the main factor directly affecting the construction quality of municipal road and bridge. This paper first introduces the definition and relevant characteristics of soft soil foundation in the construction of municipal road and bridge engineering, and expounds the influence of soft soil foundation on municipal road and bridge engineering, and then analyzes the application of soft soil foundation treatment technology combined with the basic treatment ideas of soft soil foundation in the construction of municipal road and bridge.

12 Background: Declining use of BT has prompted questions regarding the use of SBRT in HR patients. A systematic literature review was conducted to assess toxicity, and biochemical outcomes following SBRT or HDR BT boost in HR patients. Methods: A search was carried out on the PubMed and Embase databases, for studies published between 2007 and 2017, including HR patients treated with SBRT or HDR boost. Results: We identified 11250 articles, with 6 SBRT and 41 HDR boost studies eligible. The median follow-up was 3.5-5.5 and 2.6-10.3 years in SBRT and HDR boost studies, respectively. The five-year bDFS was 41%–96% in HDR and 69%–98% in SBRT boost studies. Toxicity was reported using the Radiation Therapy Oncology Group (RTOG) scale or the Common Terminology Criteria for Adverse Events (CTCAE) scale and/or validated patient reported Quality of Life (QoL) outcomes. Single SBRT and HDR studies reported 1 year IPSS scores < 7, with 2 SBRT reports of excellent outcomes by the EPIC scale. Acute grade 2 (G2) genitourinary (GU) toxicity ranged from 24-46% and 0.4-33% in SBRT and HDR boost studies, respectively. Late G2 GU toxicity occurred in 2.3-25% and 0-22% following SBRT and the HDR boost, respectively. Late grade 3 (G3) GU toxicity was reported in 0-2.3% and 0-10% with SBRT and HDR boost, respectively. Late G3 GU was reported in 0.8% (2/226) and 4% (114/2763) following SBRT and HDR boost, respectively. Acute G2 gastrointestinal (GI) was noted in 8-19% and 0-19% of SBRT and HDR boost studies, respectively. Late G3 GI was reported in 0-10% and 0-4.6% of SBRT and HDR boost studies, respectively. Late G3 GI was reported in 2% (5/226) and 0.6% (18/2829) of SBRT and HDR boost studies, respectively. Conclusions: SBRT boost may be associated with higher acute G2 but lower late G3 GU toxicity but was not shown by QoL reports, and could be due to selection bias, learning curves or other factors. Randomized trials and validated QoL instruments are needed to accurately compare SBRT to HDR boost.

Abstract Introduction The common cause of approximately 25 to 30% of all patients presenting to the neurotologist with the complaint of head-spinning is benign paroxysmal positional vertigo (BPPV) that is the commonest cause for which a patient attends a vertigo clinic. Though BPPV is very effectively treated with the canalith repositioning maneuver (CRM), a considerable percent of these patients (34–61% as per different studies)7 8 9 10 is not completely symptom-free even after a very successful maneuver (s) and complain of a new set of symptoms of light-headedness, unsteadiness, or dizziness or a combination of them termed as post-BPPV syndrome or as residual dizziness (RD) after successful correction of BPPV. Post-BPPV syndrome induces a very poor quality of life and is very incapacitating to most patients who suffer from it. Materials and Methods In Vertigo and Deafness Clinic, Kolkata, a total number of 200 patients were diagnosed with geotropic variety of BPPV in a period of 1 year from April 1, 2018 to March 31, 2019. Out of these 200 patients, the study was conducted on 178 patients who came for follow-up and also underwent all the necessary vestibular function tests. The remaining 22 patients who did not turn up for follow-up or did not undergo the tests either due to financial constraints or lack of time were excluded from the study group. The study was limited only to patients who had geotropic nystagmus and in patients with ageotropic nystagmus who were excluded from the study. One hundred seventy-eight patients of BPPV who were included in the study were managed by a protocol elaborated below devised by the first author. Results Following this protocol of BPPV management, only 23 (13%) patients after successful CRM presented with post-BPPV syndrome that is much less than the international figures of 34 to 61%. Analysis of data also showed that there was a huge psychic component in post-BPPV syndrome and that there was practically no organic vestibular deficit in post-BPPV syndrome. Conclusion Following our protocol of management of BPPV patients, which does not involve any new maneuver, only 13% of the patients complained of RD after the successful repositioning maneuvers. This is far lesser than the published international figures and this protocol may hence be tried and followed by other neurotology centers too. This protocol drastically reduces the morbidity of patients after the BPPV has been corrected by the requisite maneuvers. In our group of 23 patients who had post-BPPV syndrome out of 178 patients who had BPPV, the symptoms subsided spontaneously without medication within 3 weeks in more than 70% of patients. Only in three (13%) patients of post-BPPV syndrome, the RD persisted up to 12 weeks where drugs (selective serotonin reuptake inhibitor, benzodiazepines) and professional psychological counseling were required. None of these patients required any vestibular sedatives or the so called antivertigo drugs for amelioration of symptoms. It may hence be concluded that management of BPPV by this protocol reduces the incidence of post-BPPV syndrome and that antivertigo drugs have no role in the management of post-BPPV syndrome.

In the Department of Gastroenterology, poor compliance, psychological anxiety, fear, and other reasons result in a high rate of breach of appointment. The failure rate of colonoscopy was 6.68. This paper proposes mastering the psychological characteristics of patients and implement humanistic care services to alleviate patients’ psychological anxiety. The study found that telephone follow-up 2 days before diagnosis and treatment can let us know whether patients can come for examination and reduce the rate of nonappointment. Second, preoperative education can significantly reduce the degree of anxiety and improve the anxiety of patients. Third, the cleanliness of intestinal preparation before colonoscopy directly affects the results of colonoscopy. The incidence of missing flat adenomas due to inadequate intestinal preparation can be as high as 27%. In this paper, 7250 patients were analyzed, of which 4% failed to complete the examination, of which 32.7% were caused by unqualified intestinal preparation. The combination of telephone and network communication should be taken before colonoscopy to give education and guidance to patients, which is expected to improve intestinal preparation. To sum up, digestive endoscopic treatment technology is widely used to guide the nursing of patients after endoscopic treatment. The three effective schemes proposed in this paper can achieve higher patient satisfaction and improve the quality of nursing at the same time.
