[Standardizing the diagnosis and treatment of ocular hypertension based on evidence-based medicine].

Ocular hypertension (OHT) refers to a condition in which the intraocular pressure increases without causing glaucomatous optic nerve changes or visual field damage. The incidence rate of OHT in people over 40 years old is as high as 4% to 10%. According to the OHT Treatment Study (OHTS), the incidence of primary open angle glaucoma (POAG) among OHT patients is increasing year by year, so it is necessary to conduct long-term follow-up. This article elaborates on five major risk factors for the progression of OHT to POAG: age, intraocular pressure, vertical cup-disc ratio, pattern standard deviation of visual field, and central corneal thickness. It also summarizes other potential risk factors, such as long-term fluctuations in intraocular pressure, asymmetry of intraocular pressure and visual field between the two eyes, structural phenotypes of the optic disk, and optic disk hemorrhage. Predicting the risk of OHT progression to POAG based on risk factors, patients with different risk levels require different timing for treatment initiation and follow-up intervals. Those with higher risks should start preventive treatment earlier and have shorter follow-up intervals. Both drug therapy and selective laser trabeculoplasty can serve as initial treatment options for OHT. Combining evidence-based medicine research and individualized evaluation of treatment can enhance the clinical diagnosis and treatment level of OHT.

[Regional analysis of high risk factors of hypertensive disorders in pregnancy with organ or system impairment].

Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

[Current status of ophthalmic case registration study in the setting of real world study].

A new research concept has emerged in recent years, called real world study (RWS), which mainly relies on registration study and data management, and aims to evaluate the real effects and risks of actual clinical practice or health examination. This article compares the differences between RWS and randomized controlled trials, and summarizes the current situation of registration study in the medical field of RWS domestic and abroad, especially the current progress in the ophthalmic field. It is expected more medical centers will be able to conduct follow-ups based on the case registration system and carry out multicenter, large-scale RWS in the future.

[The efficacy of eltrombopag plus cyclosporine A in patients with transfusion-dependent non-severe aplastic anemia: a retrospective study from single center].

The main purpose of our study was to evaluate the efficacy and safety of eltrombopag plus cyclosporine A (CsA) in transfusion-dependent non-severe aplastic anemia(TD-NSAA). The clinical characteristics of 13 TD-NSAA patients who received initial treatment of eltrombopag plus CsA from 2019 to 2021 were retrospectively analyzed. The 3-month overall hematological response (OR) rate was 12/13. Until the end of follow-up, 12 patients responded, among whom 2 patients reached complete response (CR) and 9 patients reached partial response (PR) and 1 with HR. Paroxysmal nocturnal hemoglobinuria (PNH) developed in one patient at 6 months after treatment. Five of thirteen patients reported mild adverse reactions, which were all manageable. Compared with historical data, the combination of eltrombopag with CsA is an effective regimen in patients with TD-NSAA.

[Glaucoma secondary with juvenile xanthogranuloma in children:a case report].

A 4-month-old boy was admitted to the hospital after his parents noticed fog in his right eye for 27 days. Physical examination revealed multiple light brown macules on the skin. The intraocular pressure (IOP) of the right eye was 34.4 mmHg (1 mmHg=0.133kPa) and the corneal was enlarged and edema while the aqueous humor was cloudy with blood in the right eye. Yellow peripheral anterior synechia was seen on the temporal and inferior iris. Ultrasound biomicroscopy (UBM) showed extensive adhesion closure of the anterior chamber angle and the local thicken iris with the nodule. No obvious abnormality was observed in the left eye. It was confirmed as juvenile xanthogranuloma by skin lesion biopsy. IOP was normal after systemic and local therapy with corticosteroids and local IOP lowering medication. Follow up 35 months, IOP is normal without medication.

[Comparison study for the proportion of underdiagnosed zonulopathy in angle closure glaucoma].

Objective: To analyze the proportion and clinical characteristics of underdiagnosed zonulopathy in angle closure glaucoma (ACG) patients and to explore the related risk factors. Methods: Case-control study. Continuous cases of ACG patients who underwent phacoemulsification combined with intraocular lens implantation and goniosynechialysis surgery [ACG group, including acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG)] from November 1, 2020 to October 31, 2021 and age-related cataract patients who underwent phacoemulsification combined with intraocular lens implantation surgery in the same period (control group) were included. The diagnosis of zonulopathy was determined according to the intraoperative signs such as wrinkles of the anterior capsule during continuous circular capsulorhexis. The proportion of zonulopathy, preoperative diagnosis rate of zonulopathy, demographic characteristics, anterior chamber depth (ACD), axis length, difference of ACD in both eyes (ACD of the contralateral eye minus ACD of the operated eye) were compared between the two groups. The related risk factors were explored. The paired t-test (comparison between two groups of normally distributed data), non-parametric test (comparison between two groups of non-normally distributed data), Chi-square test (categorical variables), univariate and multivariate logistic regression analysis were used. Results: There were 104 ACG patients (104 eyes), including 63 AACG patients (63 eyes) and 41 CACG patients (41 eyes), and 117 controls (117 eyes). There was no significant difference in age (P=0.29) and gender (P=0.07) between the two groups. The ACG group had shallower anterior chamber (P<0.001), shorter axial length (P<0.001) and more ACD difference in both eyes (P<0.001). In the ACG group, the proportion of zonulopathy was 46.2% (48/104), which was significantly higher than that (6.0%, 7/117) in the control group (P<0.001). In the control group, only zonular laxity was found, while in the ACG group, besides the predominant zonular laxity (68.8%, 33/48), there was zonular dehiscence (31.3%, 15/48). The eyes with AACG (57.1%, 36/63) had a higher proportion of zonulopathy than those with CACG (29.3%, 12/41) (P=0.006). In the ACG group, only 14 cases (29.8%) were diagnosed preoperatively according to slit lamp examination and/or ultrasound biomicroscopy. The proportion of underdiagnosed zonulopathy was 70.8% in the ACG group (34/48). A smaller ACD was found to be related to the zonulopathy in the ACG group. All AACG cases with an ACD ≤2.0 mm and CACG cases with an ACD ≤1.9 mm had zonulopathy. Multivariate logistic regression showed that the ACD difference in both eyes (P=0.025) and the diagnosis of ACG (AACG vs. cataract, P<0.001; CACG vs. cataract, P=0.023) were independent risk factors associated with zonulopathy. Conclusions: The proportion of underdiagnosed zonulopathy among ACG patients is high. Better preoperative diagnostic methods for zonulopathy are needed. Zonulopathy is common in ACG patients, especially in AACG patients, suggesting that zonulopathy may be related to the pathogenesis of ACG. The shallower the ACD, the riskier the zonulopathy. ACD differences between two eyes and ACG types (including AACG and CACG) were related risk factors of zonulopathy.(This article was published ahead of print on the Online-First Publishing Platform for Excellent Scientific Researches of Chinese Medical Association Publishing House on March 11, 2022).

Genome-wide DNA methylation and transcription analysis in tongue and biceps femoris muscles of cloned pigs with macroglossia.

Cloned animals are prone to abnormal phenotypes such as enlarged tongue, fetal oversize, and progeria. In the present study, whole-genome bisulfite sequencing and mRNA sequencing were performed on tongue and biceps femoris muscles of cloned piglets with and without macroglossia, in an attempt to elucidate the epigenetic causes of the macroglossia phenotype. We identified 14 958 and 18 752 differentially methylated regions in the tongue and biceps femoris muscles, respectively, of macroglossia piglets and these correspond to 4574 and 4772 differentially methylated genes compared with the control group (piglets without macroglossia). Larger methylation difference was found in tongue muscle than in biceps femoris muscle. In total, 114 genes in tongue and 72 genes in biceps femoris muscles were found to be differentially expressed between the two groups. Of these differentially expressed genes in tongue muscle, 31 were also differentially methylated genes, among which DIO3 and ZIC1 were imprinting or predicted imprinting genes. These two and another six overlapping genes (ALDH1A2, MKX, MAB21L2, CA3, RANBP3L, and MYL10) are crucial factors involved in embryonic development or tissue and organ development. GO enrichment analysis suggested possible alteration of these processes. Our study provides novel molecular insights into the formation of macroglossia in cloned pigs.

[Comparative analysis of high risk factors between early-onset pre-eclampsia and late-onset pre-eclampsia].

Objective: To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia. Methods: Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared. Results: (1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion: Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Direct Detection Constraints on Dark Photons with the CDEX-10 Experiment at the China Jinping Underground Laboratory.

We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m_{V}) from 10 to 300 eV/c^{2} in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m_{V} from 0.1 to 4.0 keV/c^{2} are set from 449.6 kg-day data, with a minimum of κ=1.3×10^{-15} at m_{V}=200 eV/c^{2}.

[Medium- and long-term outcomes of cardiac assist devices after coronary artery bypass grafting in left ventricular dysfunction patients].

Objective: To evaluate the medium-and long-term outcomes of cardiac assist devices after coronary artery bypass grafting (CABG) in patients with left ventricular dysfunction. Methods: From January 2012 to May 2018, a total of 127 patients with low left ventricular ejection fraction (LVEF) value (≤40%) undergoing CABG in the Department of Cardiovascular Surgery of the First Affiliated Hospital of Zhengzhou University were selected. Meanwhile, another 2 454 cases with LVEF>55% were also enrolled as controls. Clinical data of intra-aortic balloon pump (IABP) and extracorporeal membrane oxygenation (ECMO) application were compared and analyzed. All patients were followed up at the Outpatient Clinic at different time points (3 and 6 months after surgery, then every year). Results: Compared to the control group, IABP usage (10.2% vs 0.8%), ECMO usage (6.3% vs 0.3%) and the mortality (4.7% vs 0.7%) were higher (all P<0.05) in the left ventricular dysfunction group. Additionally, Intensive Care Unit stay [(50±12) h vs (33±10) h] and the hospital stay after surgery [(15±3) d vs (11±4) d] was longer in the left ventricular dysfunction group (all P<0.05). In the left ventricular dysfunction group, LVEF at 3, 6 month and 1 year was (48±8)%, (51±9)%, and (55±9)%, respectively, and then maintained stable. Conclusions: Patients with left ventricular dysfunction who received coronary artery bypass grafting had a high rate of cardiac assist devicesuse, however, optimal perioperative management can save the lives of some patients, whose medium-and long-term outcome are good. Therefore, it is worthy of being recommended in clinical practice.

Connect the Thermodynamics of Bulk and Confined Fluids: Confinement-Adsorption Scaling.

A fluid (a gas or a liquid) adsorbed in a porous material can behave very differently from its bulk counterpart. The advent of various synthesized materials with nanopores and their wide applications have provided strong impetus for studying fluids in confinement because our current understanding is still incomplete. From a large number of Monte Carlo simulations, we found a scaling relation that allows for connecting some thermodynamic properties (chemical potential, free energy per particle, and grand potential per particle) of a confined fluid to the bulk ones. Upon rescaling the adsorbed fluid density, the adsorption isotherms for many different confining environments collapse to the corresponding bulk curve. We also reveal the intimate connection of the reported scaling relation to Gibbs theory of inhomogeneous fluids and morphological thermodynamics. The advance in our understanding of confined fluids, gained from this study, also opens attractive perspectives for circumventing experimental difficulty for directly measuring some fluid thermodynamic properties in nanoporous materials.

[Mid-term multi-center outcomes of bilateral radial artery as conduits in coronary artery bypass grafting].

Objective: To evaluate the mid-term outcomes of bilateral radial artery (BRA) grafts in coronary artery bypass grafting (CABG). Methods: All perioperative medical records and follow-up results of CABG with BRA grafts in multi-centers of China were analyzed retrospectively. Results: A total of 211 patients (170 males and 41 females) underwent CABG grafting with BRA conduits between August 2013 and September 2018, with a mean age of (56.5±9.7) years old (rang 41 to 73 years). There were 161 cases of triple-vessel disease and 50 cases of two-vessel disease. Ninety patients had diabetes mellitus (DM), 35 patients with peripheral vascular disease, 4 patients with chronic obstructive pulmonary disease and 11 with heart valve disease. Two patients underwent off-pump CABG and 209 patients accepted on-pump CABG with commitment valve surgery. There were 210 cases of total arterial revascularization and 161 cases using left thoracic artery conduits, with a graft number of 2-4 (2.7±0.9). No operation-related death occurred, atrial fibrillation happened in 12 patients, hemothorax in 7 cases, and forearm hematoma in one case, hypoxemia in 13 cases and pneumonia in one case. The duration of mechanical ventilation was (8.3±4.7) hours and the mean hospital length of stay was (7.1±2.9) days. Follow-up was completed in 191 patients (90.52%) with a duration of 3-59 (35.5±9.3) months. The mean left ventricular ejection fraction at 3 months after operation was significantly improved, compared to that of the pre-operation (61.0%±7.2% vs 47.1%±5.3%, P=0.017). All patients survived, except that one died from brain injury. No major cardiac events occurred, with a cumulative survival rate of 100% at 1 year and 99.53% at 3 year after operation, respectively. It was showed in coronary CT angiography (CTA) examination that all grafts in 132 patients were patent at the mean follow-up duration of (21.5±6.4) months. Conclusions: BRA grafts as arterial conduit in CABG are proved to be safe, easy for total arterial revascularization and have good mid-term clinical results.

Structural signature and transition dynamics of Sb2Te3 melt upon fast cooling.

Crystalline Sb2Te3 is widely studied due to its important applications in memory materials and topological insulators. The liquid and amorphous structures of this compound as well as the dynamics upon quenching, however, are yet to be fully understood. In this work, we have systematically studied the dynamical properties and local structure of Sb2Te3 at different temperatures using ab initio molecular dynamics simulations. The calculated structure factors agree well with the experimental results. The atomic number density and mean-squared displacement as a function of temperature clearly indicate three states as the temperature decreases, namely, melt, undercooled liquid and glass state, respectively. By analyzing the chemical environments and bond-angle distribution functions, we demonstrate that the most probable short-range motifs in the Sb2Te3 system are defective octahedrons, and they are connected with each other via four-fold rings. This interesting structural feature may be responsible for the high fragility and easy phase transition upon glass forming that is applied in memory devices.

[The heritability of phenotypes related to primary angle closure glaucoma].

Glaucoma is the leading cause of irreversible blindness throughout the world. Primary angle closure glaucoma (PACG) is one of the common types of this disease. Research indicates that its prevalence is always associated with many factors, including ocular anatomical characteristics and the genetic susceptibility. According to many studies, phenotypes related to PACG, such as anterior chamber depth, relative lens position and thickness, chamber angle state, and axial length, are heritable. Heritability is an important indicator to quantify this genetic tendency. Therefore, the study of heritability plays an important role in explaining the genetic susceptibility and understanding the mechanism of these diseases. This article reviews the heritability of the phenotypes that relate to PACG. (Chin J Ophthalmol, 2018, 54:864-867).

[Prioritize the standardization of clinical diagnosis and treatment of glaucoma].

The standardization of clinical diagnosis and treatment of glaucoma is crucial to ensuring the quality of medical treatment and yielding high quality results in clinical research. Based on the results of a questionnaire survey, this paper analyzes the reasons for the gap between the current situations of glaucoma diagnosis and treatment in China and the international and domestic guidelines and consensus, emphasizes the importance of standardization in clinical diagnosis and treatment, and discusses the feasible strategies for improving the standardization of diagnosis and treatment.The goal is to improve glaucoma diagnosis and treatment service capability, bridge the gap between reality and domestic and international guidelines and consensus, and further standardize the management of glaucoma as a chronic disease, through efforts in strengthening training and promoting standardization. (Chin J Ophthalmol, 2018, 54: 161-163).

Adeno-associated virus-mediated expression of myostatin propeptide improves the growth of skeletal muscle and attenuates hyperglycemia in db/db mice.

Inhibition of myostatin, a negative growth modulator for muscle, can functionally enhance muscle mass and improve glucose and fat metabolism in myostatin propeptide (MPRO) transgenic mice. This study was to investigate whether myostatin inhibition by adeno-associated virus (AAV)-mediated gene delivery of MPRO could improve muscle mass and achieve therapeutic effects on glucose regulation and lipid metabolism in the db/db mice and the mechanisms involved in that process. Eight-week-old male db/db mice were administered saline, AAV-GFP and AAV-MPRO/Fc vectors and monitored random blood glucose levels and body weight for 36 weeks. Body weight gain was not different during follow-up among the groups, but AAV-MPRO/Fc vectors resulted high level of MPRO in the blood companied by an increase in skeletal muscle mass and muscle hypertrophy. In addition, AAV-MPRO/Fc-treated db/db mice showed significantly lower blood glucose and insulin levels and significantly increased glucose tolerance and insulin sensitivity compared with the control groups (P<0.05). Moreover, these mice exhibited lower triglyceride (TG) and free fatty acid (FFA) content in the skeletal muscle, although no difference was observed in fat pad weights and serum TG and FFA levels. Finally, AAV-MPRO/Fc-treated mice had enhanced insulin signaling in the skeletal muscle. These data suggest that AAV-mediated MPRO therapy may provide an important clue for potential clinical applications to prevent type II diabetes, and these studies confirm that MPRO is a therapeutic target for type II diabetes.

Fluids in porous media. IV. Quench effect on chemical potential.

It appears to be a common sense to measure the crowdedness of a fluid system by the densities of the species constituting it. In the present work, we show that this ceases to be valid for confined fluids under some conditions. A quite thorough investigation is made for a hard sphere (HS) fluid adsorbed in a hard sphere matrix (a quench-annealed system) and its corresponding equilibrium binary mixture. When fluid particles are larger than matrix particles, the quench-annealed system can appear much more crowded than its corresponding equilibrium binary mixture, i.e., having a much higher fluid chemical potential, even when the density of each species is strictly the same in both systems, respectively. We believe that the insight gained from this study should be useful for the design of functionalized porous materials.

[The analysis of the change of the constitution of the admitted patients with glaucoma].

Objective: To analysis of the change of the constitution of the admitted patients with glaucoma in Capital Medical University affiliated Beijing Tongren Hospital between 2003-2005(group 2003) and 2013-2015(group 2013). Methods: The medical charts information of inpatient with glaucoma were collected by ICD-10 of the disease diagnosis. Statistical analysis was conducted for the change of the proportion of types, gender and age. The age difference between two groups was analyzed by rank sum test and the difference of different types of glaucoma was analyzed by chi square test. Results: Totally, 8 160 inpatients cases were included. There were 2 878 cases in the group of 2003 and 5 282 cases in the group of 2013. Between two groups, there was no statistical difference in age. The ratio of male patients decreased from 55.8% (1 607/2 878) to 51.7%(2 732/5 282) (χ(2)=23.73, P<0.05).Primary angle-closure glaucoma(PACG) was the main type (2 987/8 160, 36.6%) followed by secondary glaucoma (SG, 2 172/8 160, 26.6%). PACG reduced from 40.0% (1 151/2 878) to 34.8%(1 836/5 282) (χ(2)=21.99, P<0.01). Congenital glaucoma(CG) increased from 4.6%(132/2 878) to 8.3%(437/5 282)(χ(2)=39.04, P<0.01). Glaucoma related with trauma reduced from 27.2%(208/764) to 18.2%(256/1 408)(χ(2)=24.11, P<0.01). Glaucoma with syndrome increased from 3.8%(29/764) to 7.2%(102/1 408)(χ(2)=10.39, P<0.01). Conclusions: The constitution of the admitted patients with glaucoma in our hospital changed during the ten years. PACG was still the major type of inpatient glaucoma.(Chin J Ophthalmol, 2017, 53: 610-615).

The mortality rate of cerebrovascular disease were 154.0 per one hundred thousand(15 014/9 747 768), 155.9 per one hundred thousand(14 964/9 600 745), 143.5 per one hundred thousand(14 330/9 986 877), 135.5 per one hundred thousand(13 752/10 151 842), 130.6 per one hundred thousand(13 397/10 261 089)respectively, presented with a downward trend(P<0.05). The mortality rate of ischemic cerebrovascular disease were 62.7 per one hundred thousand(6 108/9 747 768), 74.7 per one hundred thousand(7 176/9 600 745), 72.3 per one hundred thousand(7 221/9 986 877), 70.9 per one hundred thousand(7 200/10 151 842)and 72.4 per one hundred thousand(7 431/10 261 089)respectively(P>0.05). The mortality rate of hemorrhagic cerebrovascular disease were 77.6 per one hundred thousand(7 562/9 747 768), 71.6 per one hundred thousand(6 873/9 600 745), 61.2 per one hundred thousand(6 115/9 986 877), 55.3 per one hundred thousand(5 613/10 151 842)and 46.4 per one hundred thousand(4 763/10 261 089)respectively, presented with a downward trend(P<0.05). (3)The average death age due to ischemic heart diseases of all residents was (77.0±13.1)years old, (76.4±13.2) years old among urban residents, (77.1±7.1 )years old among rural residents, (74.3±13.5)years old for male residents, (80.0±12.0) years old for female residents. The average death age due to ischemic cerebrovascular diseases of all residents was (76.4±11.9)years old, (76.5±12.3) years old among urban residents, (76.4±11.9 )years old among rural residents, (74.3±12.2)years old among male residents, (79.0±11.1) years old among female residents. From 2011 to 2015, the death age due to ischemic heart diseases were (76.3±13.5), (77.2±13.0), (76.6±13.3), (77.1±12.9)and(77.8±12.9)years old respectively; the death age due to cerebrovascular disease were (75.8±12.1), (76.3±11.8), (76.6±11.8), (76.6±12.0)and(77.1±11.9)years old respectively. The Spearman rank correlation analysis showed that the death age due to ischemic heart disease and cerebrovascular disease increased year by year in the past 5 years. (r value was 0.033 and 0.038, respectively, all P<0.01). Conclusion: From 2011 to 2015, the mortality of hemorrhagic cerebrovascular disease decreased, while the mortality of ischemic cardiovascular and cerebrovascular diseases remained unchanged among Xuzhou residents.
