ObjectiveTo analyze the impact of diabetes-related deaths on the probability of premature mortality and life expectancy in Minhang District of Shanghai from 2004 to 2023, and to provide reference data for the optimization of targeted prevention and control strategies. MethodsAll death cases involving diabetes among the registered residents of Minhang District from 2004 to 2023 were collected. The probability of premature mortality and life expectancy was computed using the abridged life table method. The average annual percent change (AAPC) was calculated with Joinpoint 4.9.0.0. The Arriaga decomposition method was employed for statistical analyses of the influence of cause-specific and age-specific mortality related to diabetes on life expectancy. ResultsThe total number of diabetes-related mortality, crude mortality, and standardized mortality for both males and females in Minhang District from 2004 to 2023 exhibited an increasing trend (P<0.001). The primary causes of death among diabetes-related cases were cardiovascular disease (37.68%), diabetes mellitus (31.95%), and malignant tumor (17.80%). From 2004 to 2023, probability of premature mortality to diabetes-related diseases demonstrated a rising trend (P<0.001), contrasting with the declining trend observed in the overall population (P=0.001). Males showed a significant upward trajectory (P<0.001), while females displayed a stable pattern. Among the diseases exerting considerable influence, cardiovascular disease and malignant tumor revealed a marked increase over time (P<0.001), whereas diabetes mellitus maintained a stable trend; both factors negatively impacted the reduction in probability of premature mortality. From 2004 to 2023, diabetes-related mortality reduced life expectancy among residents by an average of 1.22 years (-49.89%), indicating a negative impact; the reduction was 1.41 years in males and 0.90 years in females. The age groups exhibiting greater negative contributions differed by genders, namely males aged 50‒54 years and females aged 70‒74 years. Cardiovascular disease, diabetes mellitus, and malignant tumor contributed significantly to this decline (-0.46 years, -0.42 years, -0.20 years, respectively), with male experiencing higher negative contributions than females. ConclusionIn Minhang District, the rising mortality associated with diabetes-related diseases negatively impact both the reduction of the probability of premature mortality and the increase in life expectancy. This trend is primarily attributed to the rapid escalation of mortality and younger age demographic of male residents, which warrants significant attention. It is recommended that, based on the enhancement of case management, efforts should be directed towards the targeted prevention and control of risk factors and high-risk populations.

Objective:To conduct a survey on the influence of personality trait on depres-sive symptom and obesity in patients before bariatric and metabolic surgery.Methods:The retros-pective cross-sectional investigation study was conducted. Patients who underwent bariatric and metabolic surgery in The Third Xiangya Hospital of Central South University and The First Affiliated Hospital of Ji′nan University from January 1 to June 1,2024 were recruited. The survey was conducted in electronic format using the general information survey questionnaire, the patient health question-naire-9 (PHQ-9), and the Chinese big five personality inventory brief version (CBF-PI-B). Observa-tion indicators: (1) results of the questionnaire; (2) general data of patient; (3) personality trait scores for patient with different subtypes of obesity; (4) depression symptom scores for patient with different subtypes of obesity; (5) correlation analysis for patient personality trait, depressive symptom and body mass index (BMI). Comparison of measurement data with normal distribution between groups was conducted using the independent t test, and one-way analysis of variance was used for comparison among multiple groups. LSD test was used for pairwise comparison. Comparison of measurement data with skewed distribution among multiple groups was conducted using the Kruskal-Wallis H test, and Dunn Bonferroni test was used for pairwise comparison. The Spearman correlation analysis and Pearson correlation analysis were used for correlation analysis, and the mediation effect analysis was conducted using the Process 4.0 model and the Bootstrap test. Results:(1)Results of the questionnaire. A total of 146 questionnaires were distributed and collected, including 83 questionnaires from The Third Xiangya Hospital of Central South University and 63 questionnaires from The First Affiliated Hospital of Ji′nan University. Of 146 questionnaires, 137 questionnaires were valid, yielding an effective response rate of 93.836%(137/146). (2)General data of patient. Of the 137 patients who completed valid questionnaires, 52 were male with BMI of (41±5)kg/m 2, 85 were female with BMI of (38±6)kg/m 2, showing a significant difference between them ( t=2.586, P<0.05).

Objective To observe the influences on prognoses and airway acid and base levels while using anti-inflammatory and anti-reflux therapies combined with "Hezhong Fuzheng massage" for treatment of infants with gastric volvulus (GV) and gastroesophageal reflux (GER)-induced pneumonia in order to provide evidence for clinical diagnosis and treatment of such infant disease. Methods Sixty infants 1-6 months old admitted to the Department of Integrated Traditional Chinese and Western Medicine of Wuhan Children's Hospital from January 2013 to December 2015 were diagnosed as pneumonia combined with GV and GER by the chest radiograph and radiography of upper gastrointestinal tract (UGT) with iodine, and according to difference in diagnostic methods, they were divided into an observation 1 group (30 cases) and an observation 2 group (30 cases). In observation 1 group, 24-hour pH value in upper digestive tract especially the distal esophagus was dynamically monitored, while in observation 2 group, 24-hour multichannel intraluminal impedance (MII) combined with pH monitoring of esophagus was carried out. Furthermore, two control groups were set up, each 30 cases; after radiography of the UGT with iodine, the control 1 group was diagnosed as GV and GER without pneumonia and control 2 group was diagnosed as only simple GV. Treatment of infant pneumonia was carried out in accordance with the guidelines for the management of community-acquired pneumonia in children; the treatment of GV and GER included postural, dietary, prokinetic and Hezhong Fuzheng massage [acupoint selection and massage was undertaken in 5 steps: push from the palmar crease to Banmen (rectilinear pushing manipulation) 300 times, push abdominal Yin and Yang (finger-pushing massage) 200 times, palpate the abdomen (clockwise) 100 times, poking of Tianshu 100 times, poke alternately bilateral Zusanli 100 times. Once-daily massage, (15±2) minutes each time, for consecutive 7 days]. The results of pH monitoring of the distal esophagus in observation 1 group was recorded; All GER data concerning pH monitoring of observation 2 group and the results of esophagus multi-channel intra-luminal impedance combined with pH monitoring in control group were compared. After 7 days of continuous treatment, the clinical efficacy of pneumonia and GV, hospitalization time, prognosis and the changes of sputum pH before and after treatment in the two observation groups were compared. Results In two observation groups, the main type of 60 cases with GV was organoaxial volvulus, accounting for 91.67% (55 cases), and more than 60% patients exhibited sputum pH <7.0. The distal esophagus 24-hour pH dynamic monitoring in observation 1 group showed that there were 26 cases with acid reflux (86.67%), 4 cases with GER negative (13.33%), the proportion of pH < 4 in GER negative patients was significantly lower than that in moderate acid reflux patients [3.35% (0.77% - 8.08%) vs. 26.23% (15.19% - 42.87%), P < 0.05], the number of long reflux (> 5 minutes) in GER negative patients was significantly reduced than that in mild acid reflux patients [times: 2 (0-5) vs. 7 (2-15), P < 0.05], the longest time of reflux in GER negative patients was significantly shorter than that in either mild or moderate acid reflux patients [minutes: 5.9 (2.5-10.0) vs. 19.2 (5.9-51.0), 41.6 (16.9-121.0), both P < 0.05]. The 24-hour MII-pH monitoring of esophagus in observation 2 group showed that there were 30 cases with pathological reflux, mainly mild acid reflux accounting for 90%, in which the percentage of proximal reflux events was 46.07% in the total reflux events. The numbers of acid reflux and proximal reflux in the observation 2 group were significantly higher than those in the control 1 and 2 groups [1 305 (37.72%) vs. 795 (25.69%) and 136 (18.89%), 1 594 (46.07%) vs. 687 (22.20%) and 154 (21.39%), both P < 0.05]; there were no significant differences in total effective rate (100% vs. 100%, P > 0.05) and hospitalization time (days: 7.58±1.09 vs. 7.67±1.12, P > 0.05) between the two observation groups. Conclusions For the diagnosis of infant pneumonia combined with GV and GER, the first selection of chest radiograph and radiography of the UGT with iodine can identify the severity of pneumonia, whether it is complicated with GV and its classification, and whether GER exists at the same time. The estimation of 24-hour pH dynamic monitoring of the acid reflux in the upper digestive tract especially the distal esophagus is consistent with that of the 24-hour MII-PH monitoring of esophagus. Moreover, 24-hour MII-PH monitoring of esophagus can also identify non-acid reflux, resulting in the GER diagnosis more accurate. Since the proximal reflux ratio of infants with GV combined with GER and pneumonia is relatively high and easy to cause cough and aspiration. attention should be paid on early diagnosis and timely intervention to such patients. The sputum acidity test can reflect the airway acid-base level and its manipulation is simple, so by that the real time disease situation can be estimated, and aspiration of sputum also can help the treatment. The therapeutic schedule formulated by our group can elevate the therapeutic effect, improve the airway acid-base environment and benefit prognosis.

Objective To observe the clinical characteristics of infants with pertussis syndrome and the influence of gastroesophageal reflux (GER) on pertussis syndrome in small infants, and provide experience for improving curative effect. Methods ① The clinical data of 807 infants with pertussis syndrome treated at Wuhan Children's Hospital from January 2015 to June 2017 were retrospectively analyzed, in which their clinical characteristics including symptoms, signs and related physical and chemical examinations were summarized. ② Prospective randomized controlled trials were performed at the Children's Hospital of Wuhan from June 2017 to June 2018, there were 120 infants with ages < 6 months diagnosed as pertussis syndrome and simultaneously accompanied by gastric volvulus (GV) and GER, and they were randomly divided into a study group and a control group according to the date sequence of definite diagnosis, 60 cases in each group. The control group was given conventional medical treatment, while in the study group, additionally the infants received massage to restore gastric proper position and anti-reflux therapy. The clinical efficacies of two groups were observed. Results ① Retrospective analysis showed that clinically, pertussis syndrome commonly occurred in infants of ages < 6 months, accounting for 88.30% (713 cases); all cases had spastic cough, and 60.00% (484 cases) infants' coughing was severer at night. In laboratory examinations, 83.27% (672 cases) of the infants had elevated platelets (PLT), 25.03% (202 cases) had abnormal myocardial zymograms, and 70.38% (568 cases) had elevated white blood cells (WBC). In the pathogen examination, only were pathogens found in 34.8% infants, mainly single pathogen infection, accounting for 86.12%. Chest radiographs suggested 71.50% of infants with pneumonia, and 73.00% of infants with GER, among which 77.92% of infants were accompanied by GV. ② The prospective study showed that in the treatment of infants with pertussis syndrome accompanied by GV and GER, manual massage should be used timely to correct GV and simultaneously anti-reflux therapy should be given, in the aspects of time required to improve cough symptoms (days: 5.36±1.40 vs. 6.59±1.56, P < 0.01) and shortening of the hospital stay (days: 6.50±1.41 vs. 8.09±1.63, P < 0.01) in the study group were superior to those in the control group; the case of respiratory failure in the study group was lower than that in the control group [2 cases vs. 8 cases, P < 0.05]. Conclusions In pertussis syndrome, lymphocytes occupy the main proportion of WBC elevation that is an important differential criterion between pertussis syndrome and infantile pneumonia with gastric volvulus and gastroesophageal reflux. PLT elevation in pertussis syndrome suggests that attention should be paid to the elevation as that might be related to the disease prognosis. It is necessary to further investigate whether the positive pathogen discovered in the course of pertussis syndrome is a pathogenic one, and attention should also be paid to the medical examination of GV and GER in the small infants with pertussis syndrome, since early proper intervention to correct GV and GER can significantly improve their clinical efficacies.
