ABSTRACT

A variety of full 2ʹ-F/OMe-modified siRNAs were designed and synthesized, and the activity against hepatocellular carcinoma Huh-7 and HepG2 cells was evaluated. K&A DNA/RNA H-8 synthesizer was used to synthesize siRNAs, and neutral cytidinyl lipid DNCA mixed with cationic lipid CLD were used to transfect siRNA. By RT-qPCR and CCK-8 assay, the target gene silence and the proliferation of Huh-7 and HepG2 cells were detected. The siRNAs loading into Ago2 protein was detected by RNA-binding protein immunoprecipitation. Drug uptake and cell apoptosis were detected by flow cytometry, and the expression of PLK1 protein was detected by Western blot. Partial full 2ʹ-F/OMe modified siRNAs, especial siPLK1A3, increased the uptake of Huh-7 cells, enhanced their binding to Ago2 and gene silencing activity, down-regulated PLK1 protein, as well as induced more Huh-7 cell apoptosis and proliferation inhibition activity. It provides important data for the development of novel siRNA modification patterns and anti-HCC formulations.

ABSTRACT

Stable isotope tracer metabolomics tracks and analyzes the whole metabolic process of the body through the tracer atoms, which belongs to the frontier technology in the field of biomedicine. This technology is of great significance and value for explaining the pathogenesis of diseases, finding biomarkers of diseases and drug action targets. Taking the mechanism of glucose catabolism disorder in depression as an example, this paper systematically expounds the stable isotope tracer metabolomics technology and its application. The research idea of stable isotope tracer metabolomics based on unmarked metabolomics was put forward, and the research strategy of biological significance interpretation from four dimensions of metabolite isotope abundance, key metabolic enzymes, metabolic flow direction and metabolite flow was given, which broke through the bottleneck of stable isotope tracer metabolomics research technology based on overall animal experiment, and provided scientific basis for the promotion and application of this technology.

ABSTRACT

This study investigated the effect of multi-glycosides of Tripterygium wilfordii(GTW) on renal injury in diabetic kidney disease(DKD) rats through Nod-like receptor protein 3(NLRP3)/cysteine-aspartic acid protease-1(caspase-1)/gsdermin D(GSDMD) pyroptosis pathway and the mechanism. To be specific, a total of 40 male SD rats were randomized into the normal group(n=8) and modeling group(n=34). In the modeling group, a high-sugar and high-fat diet and one-time intraperitoneal injection of streptozotocin(STZ) were used to induce DKD in rats. After successful modeling, they were randomly classified into model group, valsartan(Diovan) group, and GTW group. Normal group and model group were given normal saline, and the valsartan group and GTW group received(ig) valsartan and GTW, respectively, for 6 weeks. Blood urea nitrogen(BUN), serum creatinine(Scr), alanine ami-notransferase(ALT), albumin(ALB), and 24 hours urinary total protein(24 h-UTP) were determined by biochemical tests. The pathological changes of renal tissue were observed based on hematoxylin and eosin(HE) staining. Serum levels of interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected by enzyme-linked immunosorbent assay(ELISA). Western blot was used to detect the expression of pyroptosis pathway-related proteins in renal tissue, and RT-PCR to determine the expression of pyroptosis pathway-related genes in renal tissue. Compared with the normal group, the model group showed high levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), low level of ALB(P<0.01), severe pathological damage to kidney, and high protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01). Compared with the model group, valsartan group and GTW group had low levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), high level of ALB(P<0.01), alleviation of the pathological damage to the kidney, and low protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01 or P<0.05). GTW may inhibit pyroptosis by decreasing the expression of NLRP3/caspase-1/GSDMD in renal tissue, thereby relieving the inflammatory response of DKD rats and the pathological injury of kidney.

ABSTRACT

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

ABSTRACT

Objective:To explore the role and preliminary mechanism of heparin-binding protein (HBP) in the development of acute pancreatitis (AP) through clinical analysis and animal models.Methods:(1) Clinical research: Blood samples were collected from AP patients admitted to the Second Affiliated Hospital of Anhui Medical University from January 1 to December 31, 2021 within 30 min of admission, including 20 patients with severe acute pancreatitis (SAP) and 20 patients with non-severe acute pancreatitis (NSAP). Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of HBP, syndecan-1 and hyaluronic acid (HA). Modified CT severity index (MCTSI), another 20 healthy volunteers were selected as controls (HC). Spearman correlation analysis was used to analyze the correlation between HBP and syndecan-1, HA and MCTSI. Receiver operating characteristic (ROC) curve was used to evaluate HBP to predict AP severity. (2)Animal experiment: The rat model of acute pancreatitis was prepared by intraperitoneal injection of L-arginine. In the normal control group (NC, n=8), the low molecular weight heparin (LMWH) intervention group ( n=8), and the acute pancreatitis group ( AP, n=8), the rats were euthanized 12 h later, and peripheral venous blood was collected to detect the levels of HBP, syndecan-1 and HA. Lung tissue and pancreas tissue were collected to observe the pathological damage, and the polysaccharide coating damage of vascular endothelial cells was observed under a fluoroscopy electron microscope. Results:The level of HBP at admission was significantly higher in the AP group than in the HC group, and the increase in the SAP group was more obvious. Correlation analysis showed that HBP was positively correlated with syndecan-1, HA and MCTSI. Animal studies found that the levels of HBP, syndecan-1 and HA in the AP group were significantly higher than those in the NC group. The pancreatic pathological score showed that the AP group was significantly increased, and the fluoroscopy electron microscope showed that the vascular polysaccharide coating was complete in the NC group, and the structure of the AP group was severely damaged. After LMWH intervention, the structure shedding and damage were significantly reduced, and the difference was statistically significant.Conclusions:HBP can promote the progression of AP, which is related to the destruction of the polysaccharide coating structure of endothelial cells and the increase of vascular permeability caused by HBP.

ABSTRACT

Hypertension is the most important risk factor for cardiovascular and cerebrovascular diseases, affecting the structures and functions of important organs of the body, such as the heart, brain, and kidney. At present, the prevalence of hypertension in China remains high. How to effectively curb the incidence of hypertension and reduce target organ damage in patients with hypertension is an urgent challenge that needs to be addressed. Traditional Chinese medicine (TCM), by virtue of its unique efficacies and advantages, is increasingly applied around the world. In TCM, "wind" is considered as a major constant factor in the development of hypertension. Some scholars believe that hypertension is located in collaterals, and the lesions of collaterals are also important reasons for the occurrence and development of hypertension. Collateral diseases and pathogenic wind are closely related to the development of hypertension as well as target organ damage in the heart, brain, and kidney. From the six-meridian syndrome differentiation for febrile diseases, "collateral" and "wind" are closely related to the Jueyin, with collateral diseases classified into Jueyin diseases and pathogenic wind beginning in the Jueyin. The occurrence, development, and persistence of hypertension are closely related to Jueyin diseases. The present study analyzed the pathogenesis and treatment of hypertension from "collateral" and "wind" of the Jueyin, and specifically discussed the relationship between hypertension and "collateral" and "wind" of the Jueyin. It is believed that the internal depression of wind and fire in the Jueyin results in the upward impulse of liver fire, and the deficiency of Jueyin can trigger the internal movement of liver wind and stirring wind due to collateral deficiency. External contraction in the Jueyin due to the induction of external wind is the important pathogenesis of the development of hypertension and the damage to target organs such as the heart, brain, and kidney. The therapeutic methods for both "collateral" and "wind" were also discussed based on the primary prescription for Jueyin, Wumei Pills. Six-meridian syndrome differentiation can guide the therapeutic principles for all diseases and inspire posterity. Exploring the pathogenesis and treatment of hypertension from “collateral" and "wind" of the Jueyin is of great significance in guiding the prevention and treatment of hypertension, reducing target organ damage in patients with hypertension, and improving the prognosis of cardiovascular and cerebrovascular diseases.

ABSTRACT

OBJECTIVE@#To explore the therapeutic effect and safety of acupoint thread embedding therapy in treatment of simple obesity of stomach heat and damp obstruction.@*METHODS@#A total of 144 patients with simple obesity of stomach heat and damp obstruction were randomized into an acupoint thread embedding group (72 cases, 3 cases dropped off and 1 case removed) and a sham-embedding group (72 cases, 6 cases dropped off and 3 cases removed). On the base of the lifestyle adjustment, the acupoint thread embedding therapy with PGLA thread was applied to Tianshu (ST 25), Zhongwan (CV 12), Ganshu (BL 18), Shuidao (ST 28), etc. in the acupoint thread embedding group, while in the sham-embedding group, the acupoint selection and operation were all same as the acupoint thread embedding group, but without PGLA thread embedded. In either group, the treatment was given once every 2 weeks, consecutively for 12 weeks and the follow-up was conducted for 3 months after treatment. Separately, before and after treatment as well as in follow-up, the obesity indices (body mass index [BMI], waist circumference [WC], waist-to-hip ratio [WHR] and fat percentage [F%]) were observed in the two groups. Before and after treatment, the indices of blood glucose and insulin (fasting blood glucose [FBG], fasting insulin [FINS] and insulin resistance index [HOMA-IR]), adipocyte factor indices (adiponectin, leptin [LP] and serine protease inhibitor [Vaspin]) and inflammatory factor indices (tumor nercosis factor [TNF-α], interleukin-1β [IL-1β] and interleukin-6 [IL-6]) were observed separately in the two groups. The therapeutic effect and safety were compared between the two groups.@*RESULTS@#After treatment and in follow-up, except WC and WHR in the sham-embedding group, BMI, WC, WHR and F% were all reduced as compared with those before treatment in the two groups (P<0.01, P<0.05), and the values in the acupoint thread embedding group were lower than the sham-embedding group (P<0.01). After treatment, except FBG, LP and Vaspin in the sham-embedding group, FBG, FINS, HOMA-IR, LP and Vaspin were all reduced as compared with those before treatment in the two groups (P<0.01, P<0.05), and adiponectin was increased as compared with that before treatment (P<0.01, P<0.05); the improvements in the acupoint thread embedding group were more significant than the sham-embedding group (P<0.01). After treatment, the levels of serum TNF-α, IL-1β and IL-6 in the acupoint thread embedding group were reduced as compared with the values before treatment and those in the sham-embedding group separately (P<0.01). The total effective rate was 89.7% (61/68) in the acupoint thread embedding group, higher than 19.0% (12/63) in the sham-embedding group (P<0.01). There was no severe adverse reaction reported in the two groups.@*CONCLUSION@#Acupoint thread embedding therapy with PGLA thread can alleviate obesity, regulate glucose metabolism and adipocyte factors activity, improve insulin resistance and inhibit the expression of pro-inflammatory factors in the patients with simple obesity with stomach heat and damp obstruction, and this therapy presents a satisfactory safety in treatment.

ABSTRACT

The active ingredients of Ficus hirta and Hypericum perforatum were collected from Traditional Chinese Medicine Database and Analysis Platform(TCMSP) and related papers. The potential targets of these two medicinal herbs were searched from HERB database, and those associated with microvascular angina were screened out from GeneCards, Online Mendelian Inheritance in Man(OMIM), Therapeutic Target Database(TTD), and HERB. Cytoscape was used to construct a protein-protein interaction(PPI) network of the common targets shared by the two herbs and microvascular angina based on the data of String platform. Metascape was employed to identify the involved biological processes and pathways enriched with the common targets. Cytoscape was used to draw the "active ingredient-target-pathway" network. AutoDock Vina was used to dock the core ingredients with the key targets. A total of 19 potential active ingredients and 71 potential targets were identified to be associated with microvascular angina. Bioinformatics analysis showed that phosphatidylinositol-3-kinase/protein kinase B(PI3 K-AKT), interleukin-17(IL17), hypoxia-inducible factor 1(HIF-1) and other signaling pathways were related to the treatment of microvascular angina by F. hirta and H. perforatum. Molecular docking results showed that β-sitosterol, luteolin and other ingredients had strong affinity with multiple targets including mitogen-associated protein kinase 1(MAPK1), epidermal growth factor receptor(EGFR) and so on. These findings indicated that F. hirta and H. perforatum may regulate PI3 K-AKT, IL17, HIF-1 and other signaling pathways by acting on multiple targets to alleviate oxidative stress, inhibit inflammatory response, regulate angiogenesis, and improve vascular endothelium and other functions. This study provides reference for in vitro and in vivo studies of the treatment of microvascular angina.

ABSTRACT

Objective: To confirm the impact of obstructive sleep apnea hypopnea syndrome (OSAHS) on perioperative and long-term outcome in patients with Stanford type A aortic dissection. Methods: From June 2010 to July 2017, the clinical data of 91 patients with Stanford type A aortic dissection were analyzed. Among them, 51 patients with OSAHS were included in the study group and 40 patients without OSAHS were included in the control group. After 36 months follow-up, all-cause death was regarded as the end event. The clinical baseline data, perioperative period and 36 months survival rate of the two groups were compared. Kanplan-Meier method was used to describe the 36 month survival curve of the two groups. Cox proportional risk model was used to evaluate the risk ratio (HR) and 95%CI of 36 month survival rate. Results: The mortality rate during hospitalization was 5.9% (3 cases) in the study group and 5.0% (2 cases) in the control group, and the difference was not statistically significant (χ~2=0.03, P>0.05). The actual follow-up was (36.2±1.5) months, 88 cases were followed up and 3 cases were lost. The all cause mortality rate of 36 months was 27.5% (14/51)in the study group and 10.0%(4/40) in the control group, the difference was statistically significant (χ~2=4.30, P<0.05).By Cox proportional risk model analysis, 36 months after operation, the study group was compared with the control group after adjusting for age, male, bicuspid of aortic valve, chronic obstructive pulmonary disease, anemia, preoperative pericardial tamponade, postoperative organ dysfunction, preoperative LVEF, emergency operation, Sun's operation, coronary artery bypass grafting, hypertension, cardiac arrhythmia, and advanced avulsion of distal aortic dissection The survival rate was lower, the difference was statistically significant (P<0.05).In addition to OSAHS, coronary artery bypass grafting and preoperative pericardial tamponade were also risk factors for the increase of 36 month mortality rate (HR=11.28,95%CI: 1.98-46.25, P=0.009; HR=9.08, 95%CI: 2.22-41.3, P=0.032). Conclusions: There was no significant difference in mortality during hospitalization in patients with Stanford A aortic dissection combined with OSAHS. The survival rate of 36 months after operation was lower than that of the control group.

ABSTRACT

Sleep disturbances are common in patients with stroke, and sleep quality has a critical role in the onset and outcome of stroke. Poor sleep exacerbates neurological injury, impedes nerve regeneration, and elicits serious complications. Thus, exploring a therapy suitable for patients with stroke and sleep disturbances is imperative. As a multi-targeted nonpharmacological intervention, remote ischemic conditioning can reduce the ischemic size of the brain, improve the functional outcome of stroke, and increase sleep duration. Preclinical/clinical evidence showed that this method can inhibit the inflammatory response, mediate the signal transductions of adenosine, activate the efferents of the vagal nerve, and reset the circadian clocks, all of which are involved in sleep regulation. In particular, cytokines tumor necrosis factor α (TNFα) and adenosine are sleep factors, and electrical vagal nerve stimulation can improve insomnia. On the basis of the common mechanisms of remote ischemic conditioning and sleep regulation, a causal relationship was proposed between remote ischemic conditioning and post-stroke sleep quality.

ABSTRACT

This study aims to investigate the potential mechanism of curcumin in mediating interleukin-6(IL-6)/signal transducer and activator of transcription 3(STAT3) signaling pathway to repair intestinal mucosal injury induced by 5-fluorouracil(5-FU) chemotherapy for colon cancer. SD rats were intraperitoneally injected with 60 mg·kg~(-1)·d~(-1) 5-FU for 4 days to establish a model of intestinal mucosal injury. Then the rats were randomly divided into model group(equal volume of normal saline), curcumin low, medium and high dose groups(50, 100, 200 mg·kg~(-1)), and normal SD rats were used as control group(equal volume of normal saline). Each group received gavage administration for 4 consecutive days, and the changes of body weight and feces were recorded every day. After administration, blood was collected from the heart, and jejunum tissues were collected. The levels of serum interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) were detected by ELISA, and at the same time, the concentration of Evans blue(EB) in jejunum was measured. Hematoxylin-eosin(HE) staining was used to observe the pathological state of jejunum, and the length of jejunum villi and the depth of crypt were measured. The positive expression levels of claudin, occludin and ZO-1 were detected by immunohistochemistry. Western blot was used to detect the protein expression of IL-6, p-STAT3, E-cadherin, vimentin and N-cadherin in jejunum tissues. The results showed that, curcumin significantly increased body weight and fecal weight(P<0.05 or P<0.01), decreased fecal score, EB concentration, IL-1β and TNF-α levels(P<0.05 or P<0.01) in rats. In addition, curcumin maintained the integrity of mucosal surface and villi structure of jejunum to a large extent, and reduced pathological changes in a dose-dependent manner. Meanwhile, curcumin could increase the positive expression of occludin, claudin and ZO-1(P<0.05 or P<0.01), repair intestinal barrier function, downregulate the protein expression of IL-6, p-STAT3, vimentin and N-cadherin in jejunum tissues(P<0.05 or P<0.01), and upregulate the protein expression of E-cadherin(P<0.05). Therefore, curcumin could repair the intestinal mucosal injury induced by 5-FU chemotherapy for colon cancer, and the mechanism may be related to the inhibition of IL-6/STAT3 signal and the inhibition of epithelial-mesenchymal transition(EMT) process.

ABSTRACT

Climate change has been referred to as one of the greatest threats to human health, with reports citing likely increases in extreme meteorological events. In this study, we estimated the relationships between temperature and outpatients at a major hospital in Qingdao, China, during 2015-2017, and assessed the morbidity burden. The results showed that both low and high temperatures were associated with an increased risk of outpatient visits. High temperatures were responsible for more morbidity than low temperatures, with an attributed fraction (AF) of 16.86%. Most temperature-related burdens were attributed to moderate cold and hot temperatures, with AFs of 5.99% and 14.44%, respectively, with the young (0-17) and male showing greater susceptibility. The results suggest that governments should implement intervention measures to reduce the adverse effects of non-optimal temperatures on public health-especially in vulnerable groups.

ABSTRACT

@#AIM:To evaluate the effect of the vault on corneal endothelial cells after implantation of central hole implantable lens(ICL)V4c without viscoelastic microincision.<p>METHODS: Prospective non-randomized controlled study. A total of 70 patients(137 eyes)with myopia who underwent ICL V4c implantation in our hospital from November 2017 to February 2018 were divided into low vault group(100μm<vault≤250μm, 37 eyes), medium vault group(250μm<vault≤750μm, 69 eyes)and high vault group(750μm<vault≤900μm, 31 eyes)according to the size of postoperative vault. After 1a of follow-up, the changes of corneal endothelial cell count and anterior chamber parameters were observed.<p>RESULTS:At 1wk after operation, the anterior chamber depth, anterior chamber volume and anterior chamber angle of the three groups were all decreased compared with those before operation(<i>P</i><0.05). There was no significant difference in corneal endothelial cell count among the three groups at different time points before and after surgery. The loss rate of corneal endothelial cells in the low vault group at 1wk, 3mo and 1a after surgery were about 1.2%, 1.5% and 1.7%, respectively. The loss rate of corneal endothelial cells in the middle vault group were about 0.5%, 0.7% and 1.0%, respectively. The loss rate of corneal endothelial cells in the high vault group were about 1.1%, 1.3% and 1.4%, respectively.<p>CONCLUSION:The vault in early period after ICL V4c implantation without viscoelastic microincision had no significant effect on corneal endothelial cells.

ABSTRACT

Objective:To analyze the relationship between free androgen index and insulin function in obese young men aged from 20 to 35.Methods:A total of 82 young obese men in Obesity Clinic from February to October 2019 were enrolled in the study. The subjects were divided into 3 subgroups according to free androgen index level tertiles. The blood glucose and insulin levels were tested after oral glucose tolerance test. Homeostasis model assessment for insulin resistance (HOMA-IR), homeostasis model assessment for β cell function (HOMA-β), insulin secretion index, and insulin sensitivity index (Matsuda index) were used to evaluate β cell function in oder to analyze the relationship between free androgen index and insulin function.Results:In young obese men, participants with higher free androgen index levels exhibited less waist circumference, lower body mass index, 1 h postprandial insulin, 2 h postprandial insulin, HOMA-IR level but with a higher total testosterone, sex hormone binding globulin, and Matsuda index level (all P<0.05). There was a negative correlation between the free androgen index and the HOMA-IR ( r=-0.386, P=0.016), and the correlation tended to a linear trend after adjustment for age, sex, body mass index, and waist circumference ( Ptrend=0.034). Free testosterone was positively correlated with Matsuda index ( r=0.280, P=0.004), but the correlation disappeared after adjustment ( Ptrend=0.623). The results of further regression analysis showed that the level of free testosterone index decreased by 14.1% ( OR=0.869, 95% CI0.767-0.984, P=0.028) for each increase of HOMA-IR after adjustment. Conclusion:The level of free testosterone index is a predictor of insulin resistance in obese young men, but the association between this parameter and insulin sensitivity may be caused by obesity.

ABSTRACT

Incontinentia pigmenti (IP) is an X-linked dominant disease affecting the skin, teeth, eyes and central nervous system caused by mutations in the IKBKG gene. 95% of patients are female. Skin rash is the prominent manifestation and main diagnostic basis of IP, while external skin damagesare often the factors affecting the prognosis of IP. The diagnostic criteria for IP have been updated in recent years, and Sanger sequencing remains the gold standard for the detection and analysis of IKBKG mutations. IP patients should be fully evaluated, and active treatment should be given if eye retinopathy and nervous system damage are found.

ABSTRACT

ObjectiveTo systematically review the efficacy of intervention by WeChat on medication compliance, psychotic symptom and recurrence rate of schizophrenic patients in community. MethodsDatabases including PubMed, the Cochrane Library, CBM, CNKI, Wanfang Data and VIP were searched electronically from January 1, 2011 to November 1, 2020 to collect randomized controlled trials (RCTs) about the effects of WeChat intervention on community schizophrenic patients. After two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, the meta-analysis was performed with Stata 12.0 software. ResultsA total of 381 articles were retrieved and finally 10 RCTs were included, including 1 251 patients with WeChat intervention group 641 cases and routine health education group 610 cases. Meta-analysis showed that compared with the conventional health education group, the WeChat intervention group had higher medication compliance (OR=3.05,95% CI:1.98~4.69,P<0.01), lower PANSS score (SMD=-1.05,95% CI:-1.46~-0.64,P<0.01) and relapse rate (OR=0.34,95% CI:0.24~0.48,P<0.01). ConclusionThe interactive intervention based on WeChat platform can effectively improve the medication compliance of patients with schizophrenia in the community, help to reduce the severity of psychotic symptoms and the recurrence rate.

ABSTRACT

Objective:To analyze the clinical characteristics and transthyretin ( TTR) gene mutation of a family with familial vitreous amyloidosis (FVA). Methods:A pedigree investigation was performed.The clinical data of 20 family members of a Han family with FVA treated in the Affiliated Hospital of Guizhou Medical University from May 2005 to March 2019 were collected, including demographic data and ophthalmic examination results.Nine eyes of five patients underwent vitrectomy successively, and vitreous samples collected during operation were sent for pathological examination by Congo red staining.The best corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured, and the anterior segment as well as fundus was observed under the slit lamp microscope at 1 week and 6 months after surgery.Peripheral venous blood (4 ml) was collected from 20 members in this family and DNA was extracted.The next-generation sequencing technology was used for gene detection of proband, and Sanger sequencing was performed in 20 family members including the proband.The pathogenicity of the mutation sites was analyzed according to ACMG guidelines.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Affiliated Hospital of Guizhou Medical University (No.2019-296). Written informed consent was obtained from each subject.Results:The preoperative BCVA of the nine eyes (5 patients) remained 0.1 to 0.2 in 6 eyes, and counting fingers to 50 cm in 3 eyes, and the mean value of preoperative IOP was (15.18±1.32) mmHg (1 mmHg=0.133 kPa). Cotton-wool like opacity in the vitreous and white pedal disc punctate granule on the posterior lens capsule were seen in the 9 eyes under the slit lamp microscope.Vitreous specimens of patients were Congo red stain positive.The BCVA remained 0.8 in 8 eyes and 0.6 in 1 eye at 1 week after vitrectomy, and remained 0.8 in 6 eyes, 0.6 in 2 eyes and light perception in 1 eye at 6 months after surgery.Mean values of postoperative IOP were (15.32±2.11) mmHg and (16.13±1.25) mmHg at 1 week and 6 months after surgery, respectively.Secondary glaucoma occurred in 8 eyes at 3 to 14 years postoperatively.Mean BCVA of the 13 phenotypic normal family members (26 eyes) remained 0.8 to 1.0, and the mean value of IOP was (15.52±1.15) mmHg, and abnormalities were not found in anterior segment or fundus.Additionally, two members (4 eyes) failed to take examinations.Genetic testing revealed heterozygous mutation in p. Gly103Arg of TTR gene in 15 family members.According to ACMG guidelines, the variation score was PS1+ PM2+ PP3, and it was likely pathogenic. Conclusions:The secondary glaucoma is of relatively high incidence in patients with FVA after vitrectomy.The heterozygous mutation of TTR gene (p.Gly103Arg) might be the variation site of the family with vitreous amyloidosis.
