Objective:To analyze the effects of the disease and injury spectrum on health-adjusted life expectancy (HALE) among permanent residents aged 55 and above in Shenzhen from 2016 to 2030.Methods:Based on the mortality surveillance data and the permanent resident population data in Shenzhen from 2016 to 2022, the Sullivan method was used to calculate the HALE during 2016—2022. The Bayesian age-period-cohort model and the grey system model were used to predict the HALE during 2023—2030. The HALE changes in the two periods were decomposed into the contributions of 20 categories of diseases and injuries, respectively.Results:From 2016 to 2022, the HALE increased from 31.41 years (95% CI: 30.50-32.32) to 33.57 years (95% CI: 32.47-34.67). During this period, the mortality effect of neurological disorders slowed the increase of HALE, with a reduction of 0.27 years. By 2030, it is anticipated that the HALE will reach 36.40 years (95% CI: 34.78-38.01). This is expected to be influenced by the mortality effects of nutritional deficiencies (-0.40 years) and mental disorders (-0.29 years), as well as the disability effects of musculoskeletal disorders (-0.66 years), skin and subcutaneous diseases (-0.21 years) and nutritional deficiencies (-0.13 years). Conclusion:The HALE of permanent residents aged 55 years and above in Shenzhen demonstrated an increasing trend over time. Greater attention should be paid to the adverse effects of neurological disorders, nutritional deficiencies, mental disorders, musculoskeletal disorders, and skin and subcutaneous diseases on the continuous increase of HALE in this population.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively. Conclusion The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.

ObjectiveTo assess the effects of constraint-induced movement therapy(CIMT) on sub-acute stroke patients with upper extremity motor dysfunction.Methods63 patients with hemiplegia after stroke were divided into two groups: control group(31 cases) and CIMT group(32 casese). The two groups received the regular rehabilitation training for 14 d. Then the control group went on the the regular rehabilitation training, while the CIMT group received CIMT for 14 d. All patients were assessed by the Action Research Arm Test(ARAT) and Fugl-Meyer(FMA) on the first day, the 15th day and the 30th day after the treatment.ResultsARAT score and FMA scores were higher in CIMT group than in the control group 30 d after the treatment and in CIMT group 15 days after the treatment(P<0.001).ConclusionCIMT is more effective to improve the upper limb motor function of the sub-acute stroke patients than the regular rehabilitation training.

Objective To evaluate the color Doppler ultrasonographic findings of active ankylosing sacroiliitis.Methods Thirty three patients (66 sacroiliac joints in total) with active ankylosing sacroiliitis identified by MRI and twenty eight healthy volunteers (56 sacroiliac joints) underwent color Doppler ultrasound examinations of sacroiliac joints.Degree of blood flow within and around the sacroiliac joints was evaluated by semi-quantitative scale (0 - 4 grade).For arteries, resistive index was also measured.Statistical analyses were performed to compare blood flow demonstration rate, blood flow signal scale distribution,degree of blow flow and RI value between the two groups.Results Higher blood flow demonstration rate was found in patients with active ankylosing sacroiliitis(60/66,90.1%) than control group (25/56,44.6%)( P = 0.000).The scale distribution and degree of blow flow between these two groups were statistically different (all P = 0.000) ,with mainly 2～3 grade for the patients and 0～1 grade for the control.Mean value of RI in the patients was 0.57 ± 0.07, which was lower than the control (0.66 ± 0.04, P = 0.000).Conclusions Patients with active ankylosing sacroiliitis tend to have higher degree of blood flow in sacroiliac joints and lower RI values of artery.Color Doppler ultrasound may help to evaluate the activity of ankylosing sacroiliitis.

Objective To investigate the value of Doppl er tissue imaging (DTI) in detecting chronic ischemic myocardium before and after gene transfer. Methods An Ameroid constrictor was placed around the left circumflex artery of each open-chest pig. After 4 weeks, groupⅠandⅡwere intramyocardially administrated recombinant adenovirus coding for the vascular endothelial growth factors(Ad.VEGF-B) or phosphate buffer(PB). After 4 weeks, their hearts were removed for pathological investigation. Color M-mode, two-dimensional and spectrum DTI of lateral-posterior wall before operation, 2 weeks and 4 weeks after Ameroid placement, 2 weeks and 4 weeks after administration were studied. Results Color of normal myocardium was bright, filling and distinct stratified, and of ischemic myocardium faint, local lost and cloudy stratified. After gene transfer, color filling became better and stratification distinct. Normal V S of apical four chamber view (AP-4CV) was greater than that of left ventricular papillary muscle level short axis view (LVPM-SAM)(P

Objective To observe the perfusion changes of porcine chronic ischemic myocardium before and after gene transfer by myocardial contrast. Methods Ten normal pigs were divided into two groups: groupⅠfor gene transfer(6 pigs) and groupⅡ for control(4 pigs). Myocardial contrasts were performed respectively in basic status, 4 weeks after an Ameroid constrictor was placed around the proximal left circumflex artery (LCX) and another 4 weeks after the replication deficient recombinant adenovirus coding for the vascular endothelial growth factors (Ad. VEGF)was administrated into the regional ischemic myocardium in groupⅠ, and the phosphate buffer(PB) was administrated into similar situs in groupⅡ. The perfusion of above mentioned different blood supply myocardium was observed with HP Sonos 5500 and S4 transducer by myocardial contrast. Results The normal left ventricular myocardial wall was uniformly thick and its perfusion was bright and well filling. The chronic ischemic myocardium was thinned and its echo showed the contrast defect. The echo of the myocardium for gene transfer returned to good, but the echo of the control group remained bad including some bright bits and pieces. Conclusions The blood supply of the porcine chronic ischemic myocardium was ameliorated by gene transfer. The perfusion characters of the different blood supply myocardium can objectively reflect the blood supply status of the myocardium.

Objective: To establish porcine chronic ischemic myocardium model and to evaluate ultrasonic integrated backscatter(IBS) and Doppler tissue imaging(DTI) in detecting this model. Methods: An Ameroid constrictor was placed around the porcine proximal left circumflex artery. The calibrated average image intensity (%AⅡ), cyclic variation of IBS (CVIB), the subendo-epicardical gradient index (TGI) and the spectrum of left ventricular papillary muscle level short axis view (LVPM-SAM) and apical four chamber view (AP-4CV) were measured at normal state, 2 w, 4 w, 6 w and 8 w after Ameroid placement. Results: Normal %AⅡ, CVIB and TGI were 2.29?0.32,(9.69?2.22)dB and 0.22? 0.08 respectively. After Ameroid placement, the %AII increased gradually, the CVIB decreased gradually, and the decrease was higher in subepicardium than that in subendocardium. The most obvious decrease of TGI occurred from 2 w to 4 w after Ameroid placement and became zero at 8 w(P

OBJECTIVE: To investigate the characteristics and regularity of antineoplastic medicine-induced adverse drug reaction (ADR) occurred in our hospital. METHODS: 162 antineoplastic medicine-induced ADR cases reported in our hospital from 2005 to 2008 were analyzed statistically in respect of patients’age and sex, categories of drugs, route of administration, drug combination,organs and systems involved in ADR and clinical manifestation, etc. RESULTS: Of the total 162 ADR cases, proportion of men was similar to women. 68 cases (41.98%) were old persons aged older than 60. 123 cases(75.93%) were single use of drugs, 39 cases(24.07%) were combined use of drugs. 39.51% of ADR cases were induced by antineoplastic medicine made from plants and took up the first place in terms of incidence of ADR. 36.42% of ADR cases dominantly manifested as lesion of skin and its appendants. CONCLUSION: ADR monitoring of antineoplastic medicine should be strengthened to ensure rational and standardized use of antineoplastic medicine, avoid or reduce the occurrence of severe ADR.
