Objective To investigate the prevalence and the risk factors of dyslipidemia in residents aged 40 to 80 years in Guiyang. Methods A total of 10 022 adults (2 694 men and 7 328 women) aged 40 and over were selected from Yunyan community in Guiyang urban area for this population based cross-sectional study. Data were obtained by questionnaire survey, physical examination, fasting blood glucose, and lipid measurements. The association between influential factors and dyslipidemia was analyzed by logistic regression analysis. Results The standardized prevalence of dyslipidemia in residents aged 40 years and over in Guiyang was 46. 9%, with low high-densitylipoproteincholesterol(HDL-C)29.0%,hypertriglyceridemia19.3%,hightotalcholesterol(TC)9.3%, andhighlow-densitylipoproteincholesterol(LDL-C)4.3%. Logisticregressionanalysisindicatedthatage,gender, smoking, and alcohol abuse were the risk factors of high TC and high LDL-C. Abdominal obesity was a main risk factor for both hypertriglyceridemia and low HDL-C. Conclusion The prevalence of dyslipidemia of middle-aged and aged residents in urban districts of Guiyang was on the national average level. Hypertriglyceridemia and low HDL-C were the most common types. Age and abdominal obesity were important risk factors of dyslipidemia.

Objective:
To analyze the status of sleep disorders and their influencing factors among Tibetan secondary school students in high altitude areas in China, so as to provide a reference for the improvement and intervention of sleep quality among Tibetan secondary school students in high altitude areas.
Methods:
From April to July, 2022, a questionnaire survey on demographic factors, sleep disorders, and lifestyle was conducted on 5 486 Tibetan secondary school students in the Lhasa, Shigatse, and Nagqu regions of Tibet, China, using stratified whole-group sampling. Descriptive statistics and Logistic regression analysis were used to analyze the sleep disorders of Tibetan secondary school students and their influencing factors.
Results:
The average score of PSQI for Tibetan secondary school students at high altitude was (5.67±3.23), and the detection rate of sleep disorders (PSQI>7) was 24.72% . There were significant differences in the prevalence of sleep disorders among different grades ( χ 2=23.95, P <0.01). Logistic regression analysis showed that interpersonal sensitivity, depression, anxiety, academic stress, falling asleep after midnight, sleep environment, and parental sleep disorders were positively associated with the occurrence of sleep disorders among Tibetan secondary school students ( OR =2.74, 1.68, 2.62, 1.32, 2.02, 1.85, 2.61, 1.31, 2.19, 2.88, 4.91, 2.94, 2.51, 1.36, P <0.05).
Conclusion
Tibetan secondary school students in high altitude areas have poor sleep quality and widespread sleep disorder problems, which should be given intervention and improvement. Schools and families should give secondary school students more guidance on appropriate exercise, and reduce academic stress to improve sleep quality and ensure healthy physical and mental development for secondary school students.

?AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation.?METHODS: Retrospective study. Clinical data of 105 cases ( 105 eyes ) diagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy. Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases. Preoperative and postoperative LogMar ( Logarithm of the Minimum Angle of Resolution ) visual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed.?RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes ( 86. 7%) were significantly improved postoperatively. The visual acuity of most patients was 0. 1-0. 3 ( 42 eyes, 40. 0%) and 1 patient’s visual acuity with lens subluxation reached more than 0. 8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively.? CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation. Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.

BACKGROUND:Al ogeneic hematopoietic stem cel transplantation (HSCT) is one of the effective methods in the treatment of leukemia. The haploidentical HSCT is an option for the patients who need a HSCT without a human leukocyte antigen (HLA)-matched donor. OBJECTIVE:To study the clinical efficacy of HLA-haploidentical HSCT on leukemia and its complications. METHODS:A total of 23 patients (4 cases of acute lymphoblastic leukemia, 12 of acute myelogenous leukemia, and 7 of chronic granulocytic leukemia) who had been treated with HLA-haploidentical HSCT from November 2007 to March 2015 were enrol ed. Conditioning regimen I was set as cyclohexyl nitrosourea+cytarabine+busulfan+cyclophosphamide; regimen II as cyclophosphamide+total body irradiation;regimen III as fludarabine+cytarabine+busulfan+cyclophosphamide; and regimen IV as busulfan+cyclophosphamide. Cyclosporin A, mycophenlate mofetil, antithymocyte globulin and methotrexate were used to prevent graft-versus-host disease (GVHD). Hematopoietic remodeling, complications and prognosis were observed in al patients undergoing HLA-haploidentical HSCT. RESULTS AND CONCLUSION:Of the 23 patients, 22 achieved reconstitution of the granulocyte series, and 19 achieved reconstruction of the megakaryocyte series. Additional y, there were 7 cases of acute GVHD and 4 of chronic GVHD. Transplant-related mortality was 22%(5/23) within 100 days post transplantation including graft failure, acute GVHD, intracranial hemorrhage and disseminated infections. There were 14 cases of disease-free survival from 100 days to 24 months post transplantation, 2 cases of death due to GVHD and fungal infection, or recurrence and chronic GVHD, and 2 cases of recurrence under treatment. These findings indicate that HLA-haploidentical HSCT is an effective approach for the treatment of patients with leukemia, which is worth further investigation in clinical practice.
