Objective To analyze the death rate and life loss of injuries in Jinshan District of Shanghai from 1990 to 2023, and to provide a scientific basis for the formulation of injury prevention and control measures. Methods Excel 2010 was used to establish a database for injury death reports in Jinshan District from 1990 to 2023, and the crude mortality rate, standardized mortality rate, age-specific mortality rate, potential years of life lost (PYLL), rate of potential years of life lost (PYLLR) and standardized rate of potential years of life lost (SPYLLR) were calculated. Results From 1990 to 2023, the crude mortality rate due to injuries in Jinshan District was 52.25/100 000, while the standardized mortality rate was 36.95/100 000. Based on the standardized mortality rate, the top four causes of injury-related deaths were traffic accidents, falls, drowning, and suicide. Traffic accidents ranked first as the leading cause of death for both males (19.30/100 000) and females (8.41/100 000). The top cause of death for the 0-14 years old group was drowning, the 15-64 years old group was traffic accidents, and the 65 years old and above was falls. Over the 34-year period, according to SPYLLR, the top four causes of death for both genders were consistently traffic accidents, drowning, suicide, and falls. Conclusion From 1990 to 2023, traffic accidents, falls, drowning, and suicide have been the primary causes of injury-related deaths in Jinshan District, Shanghai. It is essential to develop targeted prevention and control strategies based on the specific characteristics of these injury-related fatalities.

Objective: To investigate the achievement of the target for blood glucose control among community patients with type 2 diabetes mellitus (T2DM) and its influencing factors, so as to provide insights into developing blood glucose management strategies and intervention measures. Methods: Basic information, lifestyle, medication use, disease history, and HbA1c test results of T2DM patients aged 18 years and older and living in Jinshan District, Shanghai Municipality for more than 6 months were collected through Jinshan District Chronic Disease Follow up Management System and district-level information platform. The proportion of blood glucose achieving the control target (HbA1c<7%) was analyzed. Factors affecting the achievement of the target for blood glucose control were identified using a multivariable logistic regression model. Results: A total of 16 758 T2DM patients were included, with 7 844 males (46.81%) and 8 914 females (53.19%), and a median age of 69.00 (interquartile range, 12.00) years. There were 8 095 patients achieving the blood glucose control target, accounting for 48.31%. Multivariable logistic regression analysis showed that age (60-69 years, OR=0.749, 95%CI: 0.675-0.832; 70-79 years, OR=0.892, 95%CI: 0.801-0.993; ≥80 years, OR=1.238, 95%CI: 1.086-1.411), body mass index (overweight, OR=0.926, 95%CI: 0.863-0.993; obesity, OR=0.800, 95%CI: 0.718-0.891), disease course (6-10 years, OR=0.728, 95%CI: 0.673-0.787; ≥11 years, OR=0.534, 95%CI: 489-0.583), smoking (daily, OR=0.792, 95%CI: 0.730-0.860), drinking (daily, OR=0.788, 95%CI: 0.642-0.967), medication adherence (intermittent, OR=0.293, 95%CI: 0.271-0.317; self discontinuation, OR=0.074, 95%CI: 0.064-0.087), hypertension (OR=0.643, 95%CI: 0.588-0.703) and cardiovascular and cerebrovascular diseases (OR=0.671, 95%CI: 0.563-0.800) were the influencing factors for the achievement of the target for blood glucose control among T2DM patients. Conclusion The blood glucose control among T2DM patients is mainly affected by age, body mass index, disease course, smoking, drinking, medication adherence and comorbidities.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

Objective:To investigate the application value of intraoperative motor nerve monitoring in cervical neurogenic tumor surgery.Methods:The efficacy of intraoperative neuromonitoring (IONM) was analyzed retrospectively in 18 patients, including 6 males and 12 females, aged from 15 to 74 years, treated in Affiliated Drum Tower Hospital, Medical School of Nanjing University from June 2019 to September 2022 who underwent total cystectomy of cervical neurogenic tumors under intraoperative nerve monitoring.Results:All 18 patients had complete tumor removal, including 8 patients with tumors from the vagus nerve and 10 patients with tumors from the brachial plexus nerve. Postoperative nerve functions were normal in patients with tumors from brachial plexus nerve, and incomplete vocal cord paralysis occurred in 2 patients with tumors from vagus vagus nerve. The total incidence of motor nerve injury was 11.1% (2/18). All patients were followed up for 6 to 45 months, with no tumor recurrence.Conclusion:Intraoperative neuromonitoring has significant values in surgery of cervical neurogenic tumors, which is helpful to remove completely the tumors on the basis of protecting the nerve functions to the maximum extent.

Objective:To investigate the effect of ultrasound monitoring of inferior vena cava collapse index (IVC-CI) guiding fluid replacement on circulation in elderly patients during induction of general anesthesia.Methods:A total of 71 elderly patients who underwent elective surgery under general anesthesia and tracheal intubation at Hunan Provincial People′s Hospital from April 2021 to September 2022 were randomly divided into control group (35 cases) and observation group (36 cases) using a random number table method. Before anesthesia, both groups of patients underwent IVC ultrasound examination and calculated the IVC-CI value. For patients with IVC-CI≥40%, the observation group was given 8 ml/kg of crystal solution before anesthesia induction, while the control group was not treated. The incidence of hypotension, the use of vasoactive drugs, and the total infusion volume from anesthesia induction to skin incision were recorded in two groups. Mean arterial blood pressure (MBP), heart rate (HR), oxygen saturation (SpO 2), cardiac index (CI), and cardiac volume variability (SVV) before anesthesia (T 0), 5 min after induction (T 1), 1 min after tracheal intubation (T 2), 5 min after tracheal intubation (T 3), 10 min after tracheal intubation (T 4), and 1 min before skin incision (T 5) were recorded and compared between the two groups. Results:The incidence of hypotension (27.8% vs 60.0%) and utilization rate of vasoactive drugs (25.0% vs 48.6%) in the observation group were lower than those in the control group, and the total infusion volume during anesthesia induction was higher than that in the control group, with statistical significance (all P<0.05). SVV, CI and MBP at T 1, T 3, T 4 and T 5 were significantly different from those at T 0 in the control group ( F=3.85, 14.66, 3.96, all P<0.05). SVV, CI and MBP at T 1, T 3, T 4 and T 5 in the observation group were significantly different from those at T 0 ( F=3.51, 13.20, 4.35, all P<0.05). There was no significant difference in SVV, CI, MBP, HR and SpO 2 between 2 groups (all P>0.05). Conclusions:For the elderly patients with preoperative IVC-CI≥40%, pre-filling with 8ml/kg crystal solution before anesthesia induction can significantly reduce the incidence of hypotension and the utilization rate of vasoactive drugs in the elderly patients during anesthesia induction.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective To analyze the trend of death level and the probability of premature death caused by chronic obstructive pulmonary disease (COPD) in Jinshan District of Shanghai from 1980 to 2020, and to provide reference for the formulation of prevention and control measures of COPD. Methods The death cases of COPD in Jinshan District from 1980 to 2020 were collected through the death cause registration information system. The crude mortality, standardized mortality, age group mortality, early death probability and annual change percentage in different periods were calculated. Results From 1980 to 2020, the crude mortality of COPD in Jinshan District was 154.38/100 000, and the standardized mortality was 82.66/100,000. In the past 41 years, the standardized mortality of COPD showed a downward trend in males and females (APC=-1.79%, -2.52%, P<0.001). In the same period, the mortality of COPD in subjects aged 30-69 years old and subjects aged 70 years old and above also decreased (APC=-8.79%, -4.79%, P<0.001), and the probability of premature death caused by COPD showed a downward trend in males and females (APC=-9.61%, -10.71%, P<0.001). Conclusion The mortality rate and the probability of premature death of COPD in Jinshan District have decreased in the past 41 years. However, COPD is still one of the major chronic diseases that pose a serious threat to the health of residents in Jinshan District. Comprehensive prevention and treatment measures should be taken to reduce the mortality and the probability of premature death of COPD.

Objective:To compare the efficacy of medial patellofemoral ligament (MPFL) reconstruction using single half tunnel, double half curved tunnel and suture anchor fixation in the treatment of patellar dislocation.Methods:A retrospective cohort study was used to analyze the clinical data of 58 patients with patellar dislocation treated in Second Hospital of Lanzhou University from June 2018 to February 2021, including 22 males and 36 females, aged 12-34 years [(19.6±5.5)years]. MPFL reconstruction was performed arthroscopically using single half tunnel fixation in 20 patients (single half tunnel group), double half curved tunnel fixation in 18 (double half curved tunnel group) and suture anchor fixation in 20 (suture anchor group). The Lysholm score, International Knee Documentation Committee (IKDC) score and Tegner activity score were compared among groups before operation, at 3 months after operation and at the last follow-up. The knee range of motion was compared among the three groups at 3 months after operation and at the last follow-up. The postoperative complications of the three groups were observed at the last follow-up.Results:All patients were followed up for 9-39 months [(26.5±9.1)months]. In single half tunnel group, double half curved tunnel group and suture anchor group, the Lysholm score was (78.4±12.0)points, (88.7±7.5)points and (81.1±9.8)points at 3 months after operation, and (80.4±14.2)points, (90.9±9.0)points and (83.3±9.1)points at the last follow-up. The postoperative Lysholm score in all groups was significantly increased from that preoperatively (all P<0.01). The Lysholm score in double half curved tunnel group was significantly higher than that in other two groups at 3 months after operation and at last follow-up (all P<0.05), but there was no significant difference between other groups (all P>0.05). In single half tunnel group, double half curved tunnel group and suture anchor group, the IKDC score was (76.7±12.2)points, (78.4±8.9)points and (81.0±8.1)points at 3 months after operation, and (77.6±15.8)points, (83.2±7.8)points and (82.4±12.4)points at the last follow-up. The postoperative IKDC score in all groups was significantly increased from that preoperatively (all P<0.01), but there was no significant difference among the three groups (all P>0.05). In single half tunnel group, double half curved tunnel group and suture anchor group, the Tegner score was (4.0±1.2)points, (5.4±1.7)points and (5.3±1.7)points at 3 months after operation, and (4.1±1.4)points, (5.8±1.8)points and (5.3±2.2)points at the last follow-up. The postoperative Tegner score in all groups was significantly improved from that preoperatively (all P<0.01). The Tegner score in single half tunnel group was significantly lower than that in other two groups at 3 months after operation and at last follow-up (all P<0.05), but there was no significant difference between other groups (all P>0.05). In single half tunnel group, double half curved tunnel group and suture anchor group, the knee range of motion was (122.3±6.4)°, (121.7±7.1)° and (123.3±5.7)° at the last follow-up, which were significantly increased from (117.3±8.0)°, (115.3±7.9)° and (116.8±8.3)° at 3 months after operation (all P<0.05), with no significant difference among the three groups (all P>0.05). The postoperative complication rate was 10.0% (2/20) in single half tunnel group, 5.6% (1/18) in double half curved tunnel group, and 25.0% (5/20) in suture anchor group ( P>0.05). Conclusions:For patellar dislocation, MPFL reconstruction using single half tunnel, double half curve tunnel and suture anchor fixation have achieved satisfactory improvement of knee range of motion, but knee functional recovery is much better after double half curved tunnel fixation.

Objective:To study the relationship between the relevant chemical elements in the original surface drinking water sources and the prevalence of dental fluorosis in Bijie City, Guizhou Province, and to provide a scientific basis for further studying the distribution of dental fluorosis patients, clarifying the mechanism of endemic fluorosis, and scientifically adjusting relevant prevention and treatment policies.Methods:From August 2021 to March 2022, based on the local census data of endemic fluorosis in Guizhou Province, 385 samples of original surface drinking water sources were collected in 214 townships (towns) of Bijie City. The pH value, and contents of fluorine (F), calcium (Ca), magnesium (Mg), aluminum (Al), titanium (Ti), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni), arsenic (As), molybdenum (Mo), cadmium (Cd), barium (Ba), lead (Pb), chromium (Cr), iron (Fe), and selenium (Se) in the drinking water were determined. Taking the dental fluorosis index representing the prevalence of dental fluorosis as the dependent variable, a principal component multiple regression model was constructed based on the above chemical elements of drinking water to study the related factors affecting the prevalence of dental fluorosis, and its contribution rate was calculated.Results:The median of dental fluorosis index in 214 townships (towns) of Bijie City was 1.460. The average of pH values and contents of F, Ca, Mg, Al, Ti, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Mo, Cd, Ba and Pb of 385 drinking water samples were 6.369, and 0.209, 179.706, 16.198, 0.163, 0.987, 0.015, 0.073, 0.176, 0.027, 0.014, 0.191, 0.007, 0.005, 0.003, 0.001, 0.155, 0.005 mg/L, respectively. Six principal components ( F1 - F6) were extracted by principal component regression analysis, and the cumulative contribution rate was 72.05%. After multiple linear regression analysis, the chemical elements in drinking water were positively correlated with the prevalence of dental fluorosis in the order of Se, Fe, Cr, Mn, Ni, Cd and Cu, and negatively correlated with the prevalence of dental fluorosis in the order of Ba, F, Ti, Mo, Zn, Al, Pb, Ca, As and Mg. Conclusions:The chemical properties in drinking water of endemic fluorosis areas in Bijie City have obvious synergistic or antagonistic effects on the occurrence and prevalence of dental fluorosis in this area. The F in the drinking water may not play a decisive role in the occurrence and prevalence of local dental fluorosis.
