Objective: To investigate the prevalence and influencing factors of chronic diseases among adult residents in Hunan Province, so as to provide insights into management of chronic diseases. Methods: Permanent residents at ages of 18 years and older were sampled using a multi-stage random sampling method in Hunan Province from April to June, 2021, and participants' demographics, smoking, alcohol consumption, sleep quality and development of chronic diseases were collected using questionnaire surveys. The prevalence of chronic diseases was estimated and standardized by the seventh national population census data. In addition, the factors affecting the prevalence of chronic diseases were identified using a multivariable logistic regression model. Results: A total of qualified 9 469 adult residents were enrolled, including 4 678 men (49.40%) and 4 791 women (50.60%), with a mean age of (59.37±14.14) years. The overall prevalence and standardized prevalence rates of chronic diseases were 50.84% and 38.44%, respectively, and the prevalence and standardized prevalence rates of hypertension, protrusion of intervertebral disc and diabetes were 18.66% and 15.06%, 6.31% and 5.28%, and 4.44% and 4.18%, respectively. Multivariable logistic regression analysis revealed that women (OR=1.252, 95%CI: 1.131-1.386), age (45 years-, OR=3.699, 95%CI: 3.104-4.407; 60 years and older, OR=9.255, 95%CI: 7.743-11.064), unmarried/divorced/widowed (OR=1.170, 95%CI: 1.036-1.321), educational level (junior high school, OR=0.730, 95%CI: 0.653-0.816; high school/technical secondary school, OR=0.710, 95%CI: 0.609-0.827; diploma and above, OR=0.586, 95%CI: 0.454-0.758), monthly household income (3 000 yuan-, OR=0.846, 95%CI: 0.759-0.943; 6 000 yuan-, OR=0.819, 95%CI: 0.710-0.943; 10 000 yuan and higher, OR=0.790, 95%CI: 0.657-0.950), smoking (OR=1.528, 95%CI: 1.363-1.713), insomnia (OR=2.637, 95%CI: 2.271-3.063) statistically correlated with the development of chronic diseases. Conclusion The prevalence of chronic diseases was 50.84% among adult residents in Hunan Province in 2021, and hypertension was the predominant chronic disease. Women, the middle-aged and elderly residents, residents with a low educational level and residents with low incomes are at a high risk of developing chronic diseases.

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

Objective To explore a good of treating posttraumatic deviated nose. Methods Clinical data of 136 patients with posttraumatic deviated nose were analyzed.Closed nasal bone replacement was employed in 34 patients with the disease history of 20-30 days,while open rhino- plasty approach was employed in 102 patients with the disease history over 6 months to correct their postt- raumatic deviated nose,and straightening the septum and ectomizing the inferior turbinate were done if necessary.Results The follow-up was over one year.In the 34 patients with the disease history of 20- 30 days,the outcome was excellent in 28 cases and good in 6.In the 102 patients with the disease history over 6 months,the outcome was excellent in 81 cases and good in 21.The deformity of nose was corrected satisfactorily.Normal nasal shape and good ventilation were obtained.Conclusion Posttraumatic devi- ated nose deformities are often caused by delayed and inaccurate treatment.Closed nasal bone replace- ment can be employed for the patients with trauma history less than one month,and open rhinoplasty ap- proach and straightening the septum and restoration of the nasal shape are employed for other patients.In this way good results can be obtained.

Objective To investigate the clinical effectiveness of coronary artery bypass grafting through descending thoracic aorta in elderly patients with coronary heast disease and to decrease the post-operative complication.Methods Thirteen elderly patients underwent coronary bypass surgery with minimally invasive direct coronary artery bypass (MIDCAB).Age range from 70 to 82 years with a mean of(72.1?6.0)years.Patients suffered from multi vessel disease.Many minimally invasive techniques of“Y”blood vessel graft anastomosis,anastomosis of blood vessel graft to descending aorta,minimally invasive direct,thoracoscope assist were used.Results All patients were survived.The mean duration of intubation was (6.9?0.9) hours.The average ICU stay was (2.5?0.5)days.No patients received blood transfusion.During the short-term follow-up(3 to 14 months) patients had no complaint of angina,Conclusions The technique of“Y”blood vessel graft anastomosis,descending aorta blood vessel graft,minimally invasive direct and thoracoscope assist in combination with coronary artery bypass grafting is a safe and cost-effective new procedure for elderly patients with multi-coronary artery disease.

Objective To sum up the therapeutic results of 125 cases of tetralogy of Fallot(TOF),and ex- plore the optimal time and risk factors of opration,as well as perioperative management.Methods One hundred and thirth-one consecutive cases of TOF underwent corrective surgery.There were simple stenosis of infundibular portion in right ventricular outflow tract in 37 cases,stenosis of infundibulum and pulmonary valve in 14 cases,main pul- monary trunk and left/right pulmonary arteries stenosis in 74 cases,and pulmonary atresia in 5 cases.Autologousper- icardial conduit,or with waived were used for right ventricular outflow tract and right ventriculo-pulmonary artery connection.Other anomalies were corrected.Results The surgicalmortality was 4.0 %.The cause of death were se- rious low cardiac output syndrome(3 patients),respiratory function failure(1 patient),pericadial infection(1 pa- tient).Conclusion It is necessary to profonn corrective opration on younger TOF patients.Effetive prophylaxis and control of low cardiac output syndrome and pulmonary complication is a useful strategy.

OBJECTIVETo explore the influence of bone marrow (BM) mesenchymal stem cells (MSCs) on macrophage activation after lipopolysaccharide (LPS) stimulation.

METHODSMouse BM MSCs were isolated and purified by adherence screening, and mouse peritoneal macrophages (MPM) were collected by sodium thioglycollate peritoneal injection, and the co-culture system was established by planting macrophages on the MSCs monolayer. The grouping of experiments: group A: MPM; group B: MPM + LPS; group C: MPM + LPS + MSC; group D: MPM + LPS + MSC supernatant. Cell culture supernatants were collected to detect the changes of TNF-alpha/TGF-beta and nitrogen monoxide (NO) after stimulating macrophages with LPS for 18 hours. At the same time Escherichia coli standard strain (ATCC25922) was added into the culture system and incubated for another 24 hours, macrophages were stained and phagocytosis were examined.

RESULTSThe concentrations of TNF-alpha and NO in culture supernatants were increased significantly to (147.4 +/- 37.1) pg/ml and (59.9 +/- 8.7) micromol/L respectively after macrophage activation, however, at the present of MSC, the concentration of TNF-alpha was dramatically decreased [(97.6 +/- 30.3) pg/ml, P = 0.032], and the concentration of NO was decreased to (50.9 +/- 29.5) micromol/L (P > 0.05). The concentrations of TNF-alpha and NO were further decreased after addition of MSC supernatants [(58.3 +/- 31.5) pg/ml and (-3.4 +/- 2.3) micromol/L respectively, P < 0.01]. There was no change in the phagocytic rate and phagoindex of macrophages after activation.

CONCLUSIONSMSCs can inhibit the activation of mouse peritoneal macrophages after stimulating with LPS but has no influence on the phagocytosis.

This study was aimed to evaluate the therapeutic efficacy of bortezomib combined with autologous peripheral blood hematopoietic stem cell transplantation (autoPBSCT) for patients with multiple myeloma (MM). 5 patients underwent autologous hematopoietic stem cell transplantation. Bortezomib treatment was supplied for patients before autoPBSCT and in the conditioning of transplantation, it was also used in maintaining treatment. Patients with transplantation adopted bortezomib plus melphalan conditioning regimen. The number of infused MNC and number of CD34(+) cells were 4.06×10(8) (4.09×10(8) - 4.37×10(8))/kg and 3.98×10(6) (2.49×10(6) - 8.2×10(6))/kg respectively. The results showed that hematopoiesis was reconstituted in 5 patients, with a neutrophil cell count more than 0.5×10(9)/L at day 14 (13 - 25 days) after transplantation and platelet count more than 50×10(9)/L at day 28 (21 - 41 days) after transplantation. Transplantation-associated death was not observed. 5 patients were disease-free survival. In conclusion, treatment of bortezomib combined with autologous peripheral hematopoietic stem cell transplantation is an effective method for patients with multiple myeloma. Use of bortezomib after transplantation might still be favourable to MM patients, for survival prolongation and life quality improvement.
