The above differences were statistically significant ( P<0.05). Conclusion:The comprehensive treatment of T2DM based on syndrome differentiation and diet can significantly reduce the blood glucose indicators including FPG, 2 hPG, HbA1c, FINS and C-PR, and benefit blood pressure and blood lipids with no adverse reactions.

Objective:To analyze the trends of coronary heart disease mortality in Tengzhou city of Shandong province from 2013 to 2021.Methods:The data of coronary heart disease (ICD-10: I20-I25) from January 2013 to December 2021 were obtained from the Chronic Disease Surveillance Information System-Coronary Heart Disease Management Module of Shandong province; the population data were provided by Tengzhou Public Security Bureau. The 95% confidence interval ( CI) of the rate was calculated using the binomial exact method. The age-standardized mortality rate (ASMR) was calculated based on 2020 National Population Census. The trends of mortality rate were analyzed using the Cochran-Armitage trend test. Results:During 2013 to 2021, there were 20 667 coronary heart disease deaths in Tengzhou city, with an average of 2 296 cases per year. The male-to-female ratio was 1.09∶1, and 80.98% (16 736/20 667) of the death cases were aged 65 years or older. The crude mortality rate and ASMR of coronary heart disease were 131.84/10 5 and 168.22/10 5 in 2013, respectively. The crude mortality rate increased by 13.67% from 2013 to 2021 ( P<0.001) with an average annual increase of 1.59%; while the ASMR decreased by 18.65% from 2013 to 2021 ( P<0.05) with an average annual decease of 2.34%. The crude mortality rate of coronary heart disease in men and women showed an upward trend, with the difference in the increase for women being statistically significant ( P<0.01); while the ASMR both in men and women showed a downward trend ( P<0.001). The crude death rates from 2013 to 2021 in age groups of 65 or older for men and women decreased by 22.40% and 19.73%, respectively (both P<0.001); while the crude death rate for age groups of 44 or younger in men showed an upward trend ( P<0.05). The crude death rate among urban residents decreased by 5.22% from 2013 to 2021 with an annual decrease of 0.67% ( P>0.05); while the crude death rate among rural residents increased by 19.29% with an annual increase of 2.18% ( P<0.001). The overall crude death rate among urban residents was higher than that among rural residents (all P<0.05). Conclusions:From 2013 to 2021, the crude mortality rate of coronary heart disease in Tengzhou city of Shandong province shows an increasing trend while the age-standardized mortality rate shows a decreasing trend. The crude mortality rate of coronary heart disease in people aged 65 and above shows a decreasing trend. In addition, the change trends are different between women and men, and between urban and rural areas.

OBJECTIVETo summarize the features of clinical manifestations, laboratory tests and imaging findings of patients with cardiac amyloidosis (CA).

METHODSA total of 60 CA patients (including 41 male and 19 female patients) from 4 centers admitted between May, 2012 and November, 2013 were included in the study. The demographic data, medical history, clinical manifestations, laboratory test data, ECG, cardiac ultrasound, and cardiac magnetic resonance (CMR) imaging of the patients were analyzed.

RESULTSTwo-thirds of the 60 CA patients, were middle-aged or elderly men, and 47% of the patients had AL-CA. The clinical manifestations included exertional dyspnea (73%), pedal edema (47%), hypotension (47%), and hypertrophy of the tongue (22%); abnormal laboratory test results included albuminuria (53%) and liver (15%) and kidney (28%) dysfunction; blood routine, urine and serum immunoglobulin quantification and immunofixation electrophoresis could help the screening of AL-CA. Kidney (53%) and liver (15%) involvement was common, and 86% of AL-CA patients had kidney involvement. Typical ECG characteristics included poor R wave progression (35%), low voltage in limb leads (33%), and a pseudo infarct Q wave (30%); the latter two were more frequent in AL-CA. The characteristics of ultrasound findings included left ventricle thickening (100%), left atrial enlargement (87%) and enhanced echo of the myocardial granules(92%), and diastolic dysfunction was obvious in all the CA patients regardless of the systolic function. The DT and E/e' of the mitral annulus could be used as an index to evaluate diastolic dysfunction in early stage of the disease. Left ventricular (LV) global subendocardial late gadolinium enhancement (LGE, 81%) accompanied by right ventricular (RV) and atrial LGE was the typical characteristic of CMR, and the range of LGE in the RV and the two atria was wider in AL-CA than in non-AL-CA. NT-proBNP (97%) and cardiac troponin (53%) in CA patients were both elevated, which helped in diagnosing and assessing the severity of cardiac involvement, according to which 50% of the patients were found to be at a high risk, 43% at an intermediate risk, and 7% at a low risk.

CONCLUSIONThe combination of the features of clinical, laboratory tests and imaging findings of CA have important diagnostic and prognostic value for CA.

The surveillance data of new cases of acute myocardial infarction (AMI) from January 1, 2013, to December 31, 2021, in Tengzhou City, Shandong Province, were used to analyze the incidence rate of AMI and its change trend among residents. The age and gender standardized incidence rate was calculated based on the 7th National Population Census 2020. The Cochran-Armitage trend test was used to analyze the trend of onset time and age. From 2013 to 2021, the crude and standardized incidence rate of total AMI in Tengzhou City declined from 130.07/100 000 and 161.12/100 000 to 76.15/100 000 and 72.77/100 000 ( Z=-13.785 and -20.822, both P<0.001). The crude and standardized incidence rates of males were higher than those of females. In 2016, males aged 45-54 years old and females aged 35-64 years old increased by 33.33%, 103.65%, 106.30%, and 95.75% compared to 2015, and the differences were statistically significant ( χ2=6.512, 4.965, 25.115, and 46.004, all P<0.05). The incidence rate of AMI in men aged<35 and 35-44 years old had an upward trend. From 2013 to 2021, the incidence rate of AMI decreased by 55.15% in urban areas and 36.59% in rural areas ( Z=-8.529 and -11.235, both P<0.001).

Objective:To analyze the impact of hypertension prevention and control on the mortality rate of acute myocardial infarction (AMI) in Tengzhou City, Shandong Province from 2013 to 2021.Methods:This study was a cross-sectional study. The surveillance data of AMI deaths from January 1, 2013 (the time when hypertension prevention and control began in Tengzhou) to December 31, 2021 were collected in the coronary heart disease information management system, the mortality rate of AMI and its change trend were analyzed, and the distribution differences among residents with different characteristics were analyzed. The registered population information was obtained from Tengzhou Public Security Bureau, and the age and gender standardized mortality rate was calculated based on the data of the 7th national population census in 2020. The t test was used to compare the differences in blood pressure and laboratory items, chi-square test was used to compare the differences in mortality rate, and Cochran-Armitage trend test was used to compare the time trend and age trend of mortality rate, so as to analyze the impact of hypertension prevention and control on the mortality rate of AMI. Results:The overall crude and standardized AMI mortality rates in Tengzhou decreased from 50.87/100 000 and 63.82/100 000 to 41.08/100 000 and 38.70/100 000 from 2013 to 2021, respectively ( Z=-5.741, -10.884, both P<0.001), and double peaks were formed in 2014 and 2017. The first peak of crude and standardized mortality rate was formed in 2015 for males, which was 25.12% and 17.60% higher than that in 2013; and the first peak was formed in 2014 for females, which was 29.56% and 24.38% higher than that in 2013 ( χ2=13.200, 9.065, 14.862, 12.123) (all P<0.05). The second peaks of crude and standardized mortality were formed in 2017, with an increase of 18.17% and 17.17% for males and 25.73% and 22.34% for females from 2016 ( χ2=8.266, 9.182, 14.066, 11.105), the standardized mortality rate was 15.18%-29.01% higher in males than that in females ( χ2=6.239-19.326) (all P<0.05). The mortality rate of AMI increased with age ( Z=35.485-51.308) ( P<0.001). Compared with 2013, the mortality rate in males aged 55 to 64 years in 2015 increased by 64.29% from that in 2013, and that of females in 2017 increased by 108.48% from that in 2015; and that in females aged 35 to 44 years in 2016 increased by 373.51% from that in 2015 ( χ2=10.751, 12.805, 4.799); in 2021, the age group of male and female≥65 years decreased by 43.51% and 41.28% when compared with that in 2013, respectively ( Z=-7.333, -7.465) (all P<0.05). The mortality rate of AMI in urban areas decreased by 76.93% in 2021 when compared with that in 2016, and in rural areas it decreased by 30.28% than that in 2017. Both regions showed a downward trend ( Z=-7.560, -2.398) (both P<0.05). Conclusions:The mortality rate of AMI in Tengzhou City, Shandong Province from 2013 to 2021 shows a decreasing trend, and prevention and control of hypertension may be one of the reasons. The standardized mortality rate of males is higher than that of females, and the mortality rate decline rate in rural areas is lower than that in urban areas. The primary and secondary prevention of AMI in such populations should be strengthened.
