AIM: To evaluate the efficacy of phacoemulsification with intraocular lens implantation(PEI)combined with goniosynechialysis(GSL)and goniotomy(GT)under direct vision with gonioscope in the treatment of advanced primary angle-closure glaucoma(PACG)combined with cataract.METHODS: Retrospective case series study. A total of 62 patients(65 eyes)with advanced PACG combined with cataract who were treated in the Second Hospital of Anhui Medical University from December 1, 2021 to March 31, 2023 were enrolled, and they were divided into two groups according to different surgical methods. The control group(32 cases, 33 eyes)received PEI+GSL, whereas the observation group(30 cases, 32 eyes)received PEI+GSL+GT. The intraocular pressure(IOP), best corrected visual acuity(BCVA)and the number of anti-glaucoma medications of the two groups before surgery and at 1 d, 1 wk, 1, 3, and 6 mo after surgery were evaluated. In addition, the visual field, cup-to-disc ratio(C/D), angle open range, anterior chamber depth, and average thickness of retinal nerve fiber layer(RNFL)were evaluated before and 6 mo after surgery.RESULTS: There were significant differences in IOP and lowering range of average IOP at 6 mo between the PEI+GSL+GT group(16.68±2.65, 11.12±8.53 mmHg)and the PEI+GSL group(18.71±2.51, 8.32±4.17 mmHg; P<0.05), and there was no difference in the rate of IOP reduction(44.57%±21.79% and 35.20%±17.94%, P>0.05). The number of anti-glaucoma medications, BCVA, anterior chamber depth, and angle closure range were improved in the two groups at 6 mo after operation(all P<0.01). The number of medication reductions and the range of angle opening at 6 mo after surgery in the PEI+GSL+GT group were significantly higher than those in the PEI+GSL group(P<0.05), and there was no difference in the other indicators between the two groups(all P>0.05). There was no difference in the mean deviation of visual field, C/D and average thickness of RNFL between the two groups at 6 mo after operation compared with those before operation(all P>0.05). The complete surgery success rate of the PEI+GSL+GT group was 81%(26/32), and the conditional success rate was 94%(30/32); while those rates of the PEI+GSL group were 58%(19/33)and 76%(25/33), respectively. There were statistical significance in the success rate of surgery between the two groups(complete success rate χ2=4.275, P=0.039; conditional success rate χ2=4.040, P=0.044). No vision-threatening complications and another surgery occurred in either group.CONCLUSION: The study showed that for patients with advanced PACG with cataract, PEI+GSL+GT is more effective than PEI+GSL.

Intracellular overexpression of cytoglobin (Cygb) has been shown to reduce extracellular matrix deposition and promote liver fibrosis recovery, but its mechanism is not yet clear. This study constructed and expressed a fusion protein (TAT-Cygb) of cell penetrating peptide TAT and Cygb, to investigate the effect of fusion protein TAT-Cygb on regulating hepatic stellate cells (HSCs) ferroptosis. Cultured human hepatic stellate cells line (LX2) were treated with TAT-Cygb and erastin in vitro, respectively. The effects of ferroptosis phenotype in LX2 cells induced by TAT-Cygb, including cell viability, cell morphology, iron ion (Fe²⁺) content, lipid peroxidation product levels, and antioxidant system indicators, were investigated using trypan blue staining, transmission electron microscopy, Prussian blue staining, and reagent kits detection. After co-treatment with TAT-Cygb and ferrostain-1, the levels of Fe²⁺, reactive oxygen species (ROS), malondialdehyde (MDA), 4-hydroxynonenal (4-HNE), nicotinamide adenine dinucleotide phosphate (NADPH) and glutathione (GSH) were measured by reagent kits. The protein expression levels of alpha smooth actin (α-SMA), collagen I and fibronectin were detected by Western blot, and the protein expression level of epidermal growth factor receptor (EGFR) and desmin relevant to fibrosis were observed by immunofluorescence. The results showed that TAT-Cygb could significantly reduce the viability of LX2 cells and trigger events relevant to ferroptosis, including promoting intracellular Fe²⁺ accumulation, and inducing mitochondrial morphological changes, and intensifying lipid peroxidation products accumulation, and decreasing the level of antioxidant indexes, which played a similar role as erastin; Fer-1 significantly weakened the increase in Fe²⁺, ROS, MDA, 4-HNE levels induced by TAT-Cygb, as well as the decrease in NADPH and GSH levels, while also weakening the TAT-Cygb-induced over-expression levels of α-SMA, collagen I and fibronectin, and TAT-Cygb-induced under-expression levels of EGFR and desmin. This cellular level study indicated that TAT-Cygb can induce ferroptosis of activated HSCs. This study revealed the potential mechanism of TAT-Cygb anti-liver fibrosis, and provided the experimental basis for further research on the molecular mechanism of TAT-Cygb realizing biological function by regulating the ferroptosis pathway.

Objective To investigate the effect of core decompression combined with bone-morphogenetic proteins(BMP)activity inducing rod implantation in the treatment of early-stage femoral head necrosis.Methods Retrospective analysis of 116 patients with early-stage femoral head necrosis from June 2018 to June 2022 were divided into core decompression combined with BMP activity inducing rod group(BMP group)and allograft bone group.Sixty cases in the BMP group were treated with core decompression combined with implantation of BMP-activated induced rods,and 56 cases in the allograft group were treated with core decompression combined with bone grafting of the allograft bone by punching and compression.The differences in hip Harris scores and visual analogue scores(VAS)of pain between the two groups at preoperative,6 months postoperative and 1 year postop-erative,and the patient treatment response and femoral head survival rate at 1 year postoperative were compared.Results All patients were followed-up,and the difference between the preoperative VAS score and Harris score of the two groups was not statistically significant(P＞0.05),and the VAS score and Harris score of the two groups were significantly improved at 6 months and 1 year after operation,and the BMP group was better than the allograft bone group,with significant difference(P＜0.05).At 1 year after surgery,the Harris hip score excellence rate of the BMP group was higher than that of the allograft bone group,and the difference was statistically significant(P＜0.05);the femoral head survival rate of the BMP group was higher than that of the allograft bone group,and the difference was statistically significant(P＜0.05).Conclusions Core decompression combined with BMP activity induced rod implantation was effective in the treatment of early femoral head necrosis,which accelerated the induction of new bone formation,improved the quality of new bone,provided biomechanical support for the femoral head,and effectively avoided femoral head collapse.Moreover,it has good biocompatibility and couldbe degraded and absorbed in the body,which is worthy of clinical promotion.

Objective To investigate the safety of rigid scleral contact lenses in correcting ametropia.Methods A total of 96 patients(192 eyes)with myopia between-20.00 and 0 D and astigmatism between 0 and 3.5 D were included in this perspective study.They were divided into an experimental group(wearing rigid scleral contact lenses)and a control group[wearing rigid corneal contact lenses(RGP)],with 48 patients in each group.Eye indicators including best correc-ted visual acuity(BCVA),corneal endothelial cell density,hexagonal cell ratio,tear film break-up time(BUT),intraocu-lar pressure(IOP),corneal fluorescence staining score,conjunctival congestion score,and ciliary congestion score were measured and compared between the two groups before wearing,on the day of wearing,and 1 week,1 month,and 3 months after wearing lenses,and eye changes were observed.Results The BCVA of patients in the two groups was grea-ter than or equal to 1.00 before wearing lenses and within 3 months after wearing lenses.Compared with before wearing lenses,the corneal endothelial cell density in the experimental group slightly decreased,and the hexagonal cell ratio slightly increased at 3 months after wearing lenses,but the differences were not statistically significant(both P＞0.05).Before wearing lenses and at 3 months after wearing lenses,the corneal endothelial cell density and the hexagonal cell ratio in the experimental group were slightly higher than those in the control group,but the differences were not statistically significant(both P＞0.05).There were no significant differences in BUT and IOP between the experimental group and the control group before wearing,on the day of wearing,and 1 week,1 month,and 3 months after wearing lenses(all P＞0.05).There were no significant differences in corneal fluorescence staining score and conjunctival and ciliary congestion ratings between the experimental group and the control group before wearing lenses and at 3 months after wearing lenses(all P＞0.05).At 3 months after wearing lenses,no conjunctival or corneal edema was observed in the experimental group.Con-clusion Rigid scleral contact lenses and RGP are safe and effective in correcting ametropia;thus,they can be applied widely.

Objective: To analyze the prognosis of neonates with severe asphyxia, so as to provide insights into improvements of prognosis among neonates with severe asphyxia. Methods: Neonates with severe asphyxia born in Hangzhou Women's Hospital from 2016 to 2021 were recruited, and neonates' birth weight, gender, Apgar score, arterial blood pH value within 30 minutes after birth and maternal delivery data were collected. Outpatient follow-up was performed among neonates one year after birth, and the prognosis was evaluated with the Gesell Developmental Scale. Death or development quotient (DQ) of <75 was defined poor prognosis, and the clinical characteristics were compared between the good prognosis group and the poor prognosis group. Results: A total of 55 neonates with severe asphyxia were enrolled, including 26 boys and 29 girls, with a median birth weight of 2 845.00 g (interquartile range, 1 948.00 g). There were 52 lying-in women (3 women had twins), with a mean age of (30.56±4.08) years, including 35 women with dystocia (67.31%) and 37 primiparas (71.15%). Of 55 neonates with severe asphyxia, there were 40 neonates with good prognosis (72.73%) and 15 neonates with poor prognosis (27.27%), including 13 deaths and 2 cases with DQ of <75. The incidence of abnormal fetal position was higher in the good prognosis group than in the poor prognosis group (36.84% vs. 0%; P<0.05), and the incidence of uterine torsion or uterine rupture was higher in the poor prognosis group than in the good prognosis group (21.43% vs. 0%; P<0.05). The median Apgar score at 5 min after birth and arterial blood pH within 30 min after birth were lower in the poor prognosis group [3.00 (interquartile range, 4.00) points and (6.93±0.23)] than in the good prognosis group [6.00 (interquartile range, 4.00) points and (7.23±0.15)] (P<0.05). Conclusion Maternal uterine torsion or uterine rupture, low Apgar score at 5 min after birth, and low arterial blood pH within 30 min after birth may aggravate the poor prognosis among neonates with severe asphyxia.

Objective: To describe the distribution characteristics of tea consumption in adult twins recruited in the Chinese National Twin Registry (CNTR) and provide clues to genetic and environmental influences on tea consumption. Methods: Enrolled in CNTR during 2010-2018, 25 264 twin pairs aged 18 years and above were included in subsequent analysis. Random effect models were used to estimate tea consumption in the population and regional distribution characteristics. The concordance rate of the behavior and difference in consumption volume of tea within pairs were also described. Results: The mean age of all subjects was (35.38±12.45) years old. The weekly tea consumers accounted for 17.0%, with an average tea consumption of (3.36±2.44) cups per day. The proportion of weekly tea consumers was higher among males, 50-59 years old, southern, urban, educated, and the first-born in the twin pair (P<0.05), and lower among unmarried individuals (P<0.001). Within-pair analysis showed that the concordance rate of tea consumption of monozygotic (MZ) twins was higher than that of dizygotic (DZ) twins and the overall heritability of tea consumption was 13.45% (11.38%-15.51%). Stratified by the characteristics mentioned above, only in males, the concordance rate of MZ showed a tendency to be greater than that of DZ (all P<0.05). The differences in consumption volume of tea within twin pairs were minor in MZ among males (P<0.05), while the differences were not significant in female twins. Conclusion: There were discrepancies in the distribution of tea consumption among twins of different demographic and regional characteristics. Tea consumption was mainly influenced by environmental factors and slightly influenced by genetic factors. The size of genetic factors varied with gender, age, and region, and gender was a potential modified factor.

Logistic regression models were used to analyze the differences in study regions and age distribution of the prevalence daytime nap habit, and its correlation with the prevalence of diabetes, hypertension, coronary heart disease (CHD), stroke, chronic obstructive pulmonary disease (COPD), and chronic liver diseases.Results:Among 510 145 participants, 39.9% had daytime nap habit in summer and 20.8% had daytime nap habit all the year round. Urban-rural differences were observed in the prevalence of summer nap habit and perennial nap habit. Daytime nap in summer was common in rural areas and Suzhou, with prevalence ranged from 32.9% to 73.3%. Haikou and Liuzhou had higher prevalence of perennial nap (60.4% and 63.3%). The proportion of people with daytime nap habit all the year round increased with age ( P for trend <0.001), the proportion was highest in those aged 70- years (31.9%). Daytime nap habit in summer was positively correlated with the prevalence of diabetes, hypertension, CHD and chronic liver disease with OR of 1.10 (95% CI: 1.07-1.14), 1.03 (95% CI:1.02-1.05), 1.07 (95% CI: 1.02-1.12) and 1.07 (95% CI:1.00-1.14), respectively. Daytime nap habit all the year round was positively correlated with the prevalence of diabetes, hypertension, CHD, stroke, COPD and chronic liver disease with OR of 1.33 (95% CI: 1.29-1.37), 1.11 (95% CI: 1.09-1.13), 1.39 (95% CI: 1.33-1.45), 1.33 (95% CI: 1.26-1.41), 1.12 (95% CI: 1.08-1.16) and 1.27 (95% CI:1.18-1.37) respectively. Conclusion:There were regional and age differences in prevalence of daytime nap habit among CKB participants. Daytime nap habit, especially daytime nap habit all the year round, was positively correlated with the prevalence of major chronic diseases.

Objective:To evaluate the correlation of dietary patterns with low muscle mass, strength and quality in Chinese adults.Methods:Based on the second resurvey of China Kadoorie Biobank, factor analysis was conducted to derive dietary patterns from 20 food groups. Low muscle mass, strength, and quality were defined as the sex-specific lowest quintile of appendicular skeletal muscle mass index (ASMI), total skeletal muscle mass index (TSMI), handgrip strength and arm muscle quality (AMQ) according to Asian Working Group for Sarcopenia recommendations. Logistic regression models were used to evaluate the correlation of dietary patterns with low muscle mass, strength, and quality.Results:Two major dietary patterns were extracted. The balanced dietary pattern was characterized by the intake of a variety of foods, whereas the rice-meat dietary pattern was characterized by high intakes of rice, meat, poultry and fish. Individuals who had the highest quintile score of the balanced dietary pattern were less likely to have low TSMI, handgrip strength or AMQ( OR=0.83, 95% CI: 0.74-0.95 for low TSMI; OR=0.64, 95% CI: 0.56-0.74 for low handgrip strength; OR=0.82, 95% CI: 0.72-0.93 for low AMQ; for trend P<0.05). And those who scored higher on the rice-meat dietary pattern had lower risk of low muscle mass and strength ( OR=0.67, 95% CI: 0.55-0.82 for low ASMI; OR=0.69, 95% CI: 0.56-0.85 for low TSMI; OR=0.74, 95% CI: 0.60-0.91 for low handgrip strength; for trend P<0.05). Conclusion:Individuals followed the balanced dietary pattern, as well as those who followed the rice-meat dietary pattern, had better levels of skeletal muscle mass, strength and quality.

Objective:To explore the correlation between chronic diseases and muscle mass, strength and quality in adults in China.Methods:Based on the second resurvey of China Kadoorie Biobank (CKB) in 2013-2014, logistic regression models were used to analyze the correlation of different types, number and duration of chronic diseases with low muscle mass, handgrip strength and muscle quality.Results:The prevalence rate of diabetes, coronary heart disease (CHD), stroke and chronic obstructive pulmonary disease (COPD) were 9.6%, 5.8%, 3.2% and 26.8%, respectively, and 38.8% of the participants had at least one disease, and they were more likely to have low handgrip strength and low arm muscle quality (AMQ), and the longer the chronic diseases duration, the higher the risk. The ORs (95% CIs) for low handgrip strength and low AMQ in patients with 1 chronic disease for more than 10 years was 1.64 (1.42-1.90) and 1.83 (1.60-2.10), respectively. The ORs (95% CIs) for low handgrip strength were 1.26 (1.17-1.37), 1.42 (1.23-1.64) and 2.27 (1.55-3.32) and the ORs (95% CIs) for low AMQ were 1.28 (1.18-1.38), 1.67 (1.46-1.92) and 2.41(1.69-3.45), respectively, in patients with 1, 2, ≥3 chronic diseases, the correlation showed a linear trend ( P for trend <0.001). Diabetes, CHD and stroke were positively correlated with low handgrip strength and low AMQ. Compared with participants without COPD, COPD patients were more likely to have low appendicular skeletal muscle mass index (ASMI), low total skeletal muscle mass index (TSMI) and low handgrip strength, and the risk was positively correlated with disease duration. Conclusions:Patients with chronic diseases were more likely to have lower muscle strength and muscle quality, especially the patients with multi diseases and longer disease duration. The proportion of low handgrip strength and low AMQ was higher in patients who reported multi-prevalence and longer duration of chronic diseases.
