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 evaluate the safety and effectiveness of robot-assisted coronary artery bypass(RACAB).Methods:We retrospectively analyzed the clinical outcomes from 252 consecutive patients who underwent RACAB in our center between April 2021 and August 2023. The internal mammary artery(IMA) was harvested using the skeletonized technique with the assistance of the robotic system. Then, graft-to-target vessel anastomoses were performed via a 4-6 cm left fifth intercostal thoracotomy. Coronary angiography or coronary CTA was routinely performed before discharge.Results:149 patients(59.1%) underwent multi-vessel coronary bypass. 140 patients(55.6%) underwent total arterial bypass grafting, with 131 patients(52.0%) undergoing RACAB with in situ bilateral IMA. IMA harvesting failed in 6 patients(1.6%). One patient(0.4%) was assisted by extracorporeal circulation, and 5 patients(2.0%) underwent re-thoracotomy postoperatively. The patency rate of grafts was 96.6%(449/465). The 12-month and 24-month survival rate were 97.8% and 96.5% respectively; The 12-month and 24-month MACCE-free survival rate were 95.2% and 92.6%, respectively.Conclusion:RACAB is safe and feasible. With the assistance of the robotic system, in situ bilateral IMA can be obtained and bypassed to all target vessels territory. Extended follow-up is warranted.

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.

The Ehlers-Danlos syndrome(EDS)is a rare inherent connective tissue disorder.The prev-alence of EDS in the population is estimated at one out of ten thousand to one out of a hundred thousand.The vascular EDS(vEDS)are rare among the subtypes but are the worst in prognosis.The article reports a case of vEDS admitted to the hospital.The patient was a young man complaining of a sudden onset of aphasia in right hemiparalysis and severe left abdominal pain for unknown reasons.The diagnosis was made after the genetic testing.The patient suffered from vEDS.Then,the multi-disciplinary team(MDT)made a treatment plan tailored to this young patient.The complexity in classification and delusive presentations of the EDS make the correct diagnosis very challenging.This article hopes to report this case and to share the experiences to the bet-ter understanding of this disease.

AIM: To establish individualized drug therapy strategy for patients with rejection and hyperglycemia after liver transplantation. METHODS: Clinical pharmacist collaborated with the surgeons and participated in the diagnosis and treatment of rejection and hyperglycemia after liver transplantation. Taking together liver function, therapeutic drug monitoring, drug-drug interactions between tacrolimus and wuzhi capsule, individualized drug therapy was adapted to improve the prognosis. RESULTS: The patient recovered well and survived in good health till now. CONCLUSION: It is highly suggested that clinical pharmacists actively involved in treatment of more severe and difficult-to-treat disease and design the individualized dosing regimens. This will largely contribute in reduced adverse drug reaction, improved safety and effectiveness in drug use as well as the quality of life in the "post-transplantation era".

Objective:To evaluate the accuracy of diffusion weighted magnetic resonance imaging (DWI-MRI) combined with high resolution temporal bone CT (HRCT) in the location diagnosis of middle ear cholesteatoma and its value in the postoperative follow-up.Methods:134 patients with inital cholesteatoma and 22 patients with suspected recurrent cholesteatoma were selected for HRCT, conventional MRI and DWI examination. Based on the intraoperative and pathological diagnosis, DWI and HRCT images were combined to evaluate the consistency between the lesion location and invasion area of the initial cholesteatoma and intraoperative lesions. The results of HRCT and DWI in the diagnosis of recurrent middle ear cholesteatoma were statistically analyzed to evaluate their diagnostic efficacy.Results:The accuracy rate of DWI combined with HRCT was 90.3%.The sensitivity, specificity, positive predictive value and negative predictive value of HRCT and DWI in the diagnosis of recurrent middle ear cholesteatoma were 27.8%, 75.0%, 83.3%, 18.8% and 100%, 75.0%, 94.7% and 100%, respectively, and the Kappa values consistent with the pathological results were 0.024 and 0.843, respectively. Chi-square test confirmed that there were differences in the diagnosis between groups ( P<0.001). Conclusions:Combined with the high sensitivity of DWI and the high resolution of HRCT, the accuracy of preoperative positioning of the newly diagnosed cholesteatoma can be improved and surgery strategy can be guided. DWI is also of high diagnostic value for recurrent cholesteatoma in the middle ear.

Objective:To study the epidemic and etiologic characteristics of influenza virus(Flu)and respiratory syncytial virus (RSV) infections in outpatient influenza-like illness(ILI)cases of children under 10 years of age in Gansu province in 2018 And to provide evidences for diagnosis, treatment, control and prevention of Flu and RSV infections in Gansu province.Methods:A total of 8 559 pharyngeal swab samples of ILI outpatients cases were tested with real-time fluorescent PCR to detect Flu, 3 436 of which were detected by RT-PCR for RSV.Results:Of the 8559 specimens, 934 (10.91%) samples were positive for Flu. Among them, 431 were positive for H1N1, 70 were positive for H3N2, 428 were positive for Flu B, 5 were mixed; 320 of the 3436 (9.31%, ) samples were positive for RSV. There were significant differences in the positive rates of Flu and RSV among 14 cities and prefectures ( χ2=56.99, χ2=263.34, Р< 0.01). Influenza reached its peak in January 2018 with a positive rate of 50.70%. Flu B/Yamagata strain (53.53%) and A H1N1 (39.93%) were prevalent simultaneously. The peak of RSV epidemic was from February to April, the positive rate was 13.98%. The RSV positive rate of children under 5 years of age was 10.11%, higher than that of children over 5 years of age was 6.94%. There was statistical significance ( χ2=7.67, Р<0.01). Conclusions:RSV and influenza viruses are the main pathogens in ILI cases of children under 10 years of age. There are epidemic peaks in winter and spring every year. It is suggested that the monitoring of RSV and the development and application of vaccine should be strengthened.

OBJECTIVETo study the promoter methylation status of SFRP genes and the effect of 5- aza- 2'- deoxycytidine (5- Aza- CdR)induced apoptosis via Wnt/β- catenin pathway by demethylation in Jurkat cells.

METHODSJurkat cells were treated with different concentrations of 5- Aza- CdR. The cell proliferation level of Jurkat cells was detected by MTT assay. Apoptosis was evaluated by flow cytometry. Methylation- spcific PCR (MSP) was used to determine the methylation status of SFRP genes. The expressions of SFRP genes were detected by real time fluorescence quantitative PCR. The mRNA expression levels of survivin, c- myc and cyclin- D1 were analyzed by RT- PCR. Western blot was used to detect the levels of β-catenin protein.

RESULTSCompared with control group, the different concentrations of 5-Aza-CdR could significantly inhibit the proliferation of Jurkat cells in a time-dose dependent manner (P<0.05). After being treated by 5- Aza- CdR for 48 hours, the cell early apoptosis rate in experiment group was significantly higher than that in control group (P<0.05). The promoters of SFRP1, SFRP2, SFRP4, SFRP5 genes were hypermethylation state in the control group, after being treated by 5-Aza-CdR for 72 hours, the brightness of SFRP1, SFRP2, SFRP4, SFRP5 genes' methylation strips weakened in a dose- dependent manner. SFRP mRNA expression increased (P<0.05) when 5- Aza- CdR concentration increased, and the level of β- catenin protein was dampened in a dose- dependent manner (P<0.05). As compared to the control group, the mRNA expressions of associated apoptosis genes survivin, c-myc and cyclin- D1, respectively were obviously down- regulated in a dose- dependent manner (P<0.05).

CONCLUSIONThe effect of demethylation could up- regulate SFRP genes expressions by reversing its hypermethylation and induced apoptosis by down-regulation of β-catenin and associated apoptosis genes.
