Status of depressive symptoms of senile cataract patients and the influence of self-perceived burden / 四川精神卫生

BackgroundElderly cataract patients with depressive symptoms have heavier self-perceived burden， and worse vision-related quality of life compared to patients without depressive symptoms， resulting in the increase of family burden. Most previous studies showed that family relationship and vision were the main factors leading to depression in elderly cataract patients， and ignored the effects of self-feeling and complicated diseases on the psychological state of elderly cataract patients. ObjectiveTo explore the relationship between depressive symptoms， self-perceived burden and postoperative vision-related quality of life in elderly cataract patients， and to analyze the risk factors of depressive symptoms. So as to provide references for targeted psychological intervention in this population. MethodsA total of 104 elderly cataract patients admitted to Jiangsu Province Hospital （The First Affiliated Hospital with Nanjing Medical University） from July 1， 2020 to December 31， 2022 were included. General information， self-perceived burden and postoperative vision-related quality of life were investigated by self-designed questionnaire， Patients' Health Questionnaire depressive Scale-9 item （PHQ-9）， Self-Perceived Burden Scale （SPBS） and National Eye Institute Visual Function Questionnaire-25 （NEI-VFQ-25）. Pearson correlation analysis was performed to analyze the correlation among PHQ-9， SPBS and NEI-VFQ-25 scores. Logistic regression analysis was used to analyze the influencing factors of depressive symptoms in eldery cataract patients. ResultsA total of 100 elderly cataract patients completed an effective questionnaire survey. Among the participants， 31 cases （31.00%） were found to have depressive symptoms. The depressive group exhibited significantly higher SPBS score （t=11.062， P<0.01） and significantly lower NEI-VFQ-25 score （t=-5.235， P<0.01） than those of the non-depressive group. Pearson correlation analysis showed a positive correlation between PHQ-9 and SPBS score （r=0.485， P<0.01）， and a negative correlation between PHQ-9 and NEI-VFQ-25 score （r=-0.440， P<0.01）. Complicated with diabetes （OR=1.441， P<0.01）， osteoarthritis （OR=1.324， P<0.05） and high SPBS score （OR=1.340， P<0.05） were risk factors of depressive sympptoms in elderly cataract patients. ConclusionThe detection rate of depressive symptoms in elderly cataract patients is higher， and postoperative vision-related quality of life in elderly cataract patients complicated with depressive symptoms is poor. Risk factors include diabetes， osteoarthritis and high self-perceived burden. ［Funded by 2022 Jiangsu Province Elderly Health Scientific Research Project （number， LKM2022019）］

Preparation and properties of injectable minocycline hydrochloride microsphere depot / 中国药科大学学报

@#To prepare a minocycline hydrochloride microsphere depot and evaluate its release performance and physicochemical properties, poly (lactic-co-glycolic acid) (PLGA) was used as raw material, the minocycline hydrochloride microspheres were prepared by electrospray, and the morphology and size distribution of the microspheres were characterized by polarizing microscopy and scanning electron microscopy (SEM). The microspheres were then mixed with sucrose acetate isobutyrate (SAIB) depot at a ratio of 1:10 to form a minocycline hydrochloride microsphere depot, and its release performance and porosity changes were evaluated. The results showed that the microspheres had smooth surface and the diameter was (5.294 ± 1.222) μm. After the microspheres were added into SAIB depot, the burst release of minocycline hydrochloride significantly decreased from 60% to 3.27% at the first day, and then the release lasted for 42 days . Additionally, the porosity of the depot increased rapidly from (12.53 ± 0.43)% to (32.53 ± 0.43)% during days 0-15, and increased slowly from (32.53 ± 0.43)% to (33.81 ± 0.54)% during days 15-45. The minocycline hydrochloride microsphere depot prepared in this study is expected to be an effective way for the application of minocycline hydrochloride for its good release performance and simple preparation process.

Maxillary sinus floor augmentation: with or without bone grafting / 中国组织工程研究

BACKGROUND: Insufficient bone mass in the posterior maxilla region often increases the difficulty of dental implantation. The application of maxillary sinus floor elevation successfully solves this problem. In the surgery bone grafting can be used to obtain sufficient bone mass. However, nonuse of graft materials can shorten the cycle of patient's treatment and reduce trauma and cost. OBJECTIVE: Combining the latest relevant research trends, to review the advances in the study of maxillary sinus floor elevation with and without bone grafting. METHODS: The first author searched PubMed, VIP, WanFang and CNKI databases using computer for relevant articles published from January 1985 to August 2018. The key words were "dental implant, maxillary sinus, bone augmentation, bone substitute" in English and Chinese, respectively. Finally, 78 articles were included in result analysis after screening and summarizing. RESULTS AND CONCLUSION: Ideal results can be achieved in the maxillary sinus floor elevation with or without simultaneous bone grafting In addition, the nonuse of grafting materials have the advantages of simplifying surgical procedures, shortening treatment cycles, reducing trauma and pain, reducing treatment costs, reducing complications and failure rates, thus gaining the favor of doctors and patients. Therefore, the maxillary sinus floor elevation without simultaneous bone grafting will be the primary choice of the doctors engaged in dental implantation in the future.

Research advances in genetic susceptibility to non-alcoholic fatty liver disease / 临床肝胆病杂志

Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases, with complicated etiology and pathogenesis. As a heredity-environment-metabolism-stress disease, the genetic factors play an important role in the pathogenesis of NAFLD. In order to identify the role of genetic factors in the pathogenesis of NAFLD and to find out new clinical therapeutic targets, the present review summarizes the susceptibility genes of NAFLD, especially those identified by genome-wide association study, including the genes of patatin-like phospholipase domain-containing 3, leptin receptor, adiponectin, and tumor necrosis factor-ɑ.

Association between Adiponectin polymorphisms and nonalcoholic fatty liver disease in Han Chinese popu-lation in Qingdao / 实用医学杂志

Objective To investigate the association between the Adiponectin rs266729 and rs2241766 gene polymorphisms and nonalcoholic fatty liver disease in the Han Chinese population residing in Qingdao. Methods Adiponectin rs266729 and rs2241766 gene polymorphisms were genotyped in patients with NAFLD (n = 336) and healthy controls (n = 280) using polymerase chain reaction (PCR). Serum lipid profiles and adiponectin levels were determined using biochemical methods. Statistical analyses were performed using Pearson Chi square test, logistic regression analysis, t test, linear regression analysis. Results We found a significant association between the Adiponectin rs266729 genotype frequencies and allele frequencies between NAFLD pa-tients and controls (χ2= 9.929, P = 0.007; χ2= 9.809, P = 0.002). After adjustment of confounding factor, the rs266729 G allele was associated with an increased risk of NAFLD compared to the C allele (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008) No significant differences were found in the rs2241766 genotype frequencies and allele frequencies between NAFLD population and the controls (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008). Conclusion The Han Chinese in Qingdao carrying the rs266729 G allele are at increased risk of NAFLD.
