Keratoconus is a blinding corneal disease characterized by central or paracentral corneal thinning and conical ectasia, and usually happens in adolescence. Currently, the etiology of keratoconus is unclear. Multiple studies have identified an association between genetics, eye rubbing, allergic diseases, ultraviolet exposure and keratoconus. Recently, several studies identified that sex hormones also played important roles in the pathogenesis of keratoconus. The disturbance of sex hormones may increase the risk of occurrence and progress of keratoconus. This review aims to summarize the pathophysiological effects of sex hormones on the cornea, clarify the effects of sex hormones on keratoconus and its related inflammatory or immune mechanisms, and explore the role of sex hormones in the early diagnosis and treatment of keratoconus, providing reference and help for clinical work.

‍ ObjectiveTo investigate the serum level of HBV RNA in untreated or treatment-experienced patients with chronic hepatitis B （CHB） and the correlation between serum HBV RNA level and the duration of antiviral therapy with nucleos（t）ide analogues （NAs）. MethodsA total of 300 patients with CHB who attended Department of Infectious Diseases in The First Affiliated Hospital of Shihezi University School of Medicine from February to July， 2022， were enrolled as subjects. Related clinical data were collected， and according to the duration of antiviral therapy， they were divided into untreated group with 73 patients， treatment duration ≤1 year group with 91 patients， and treatment duration >1 year group with 136 patients. Serum HBV RNA load， HBV DNA load， and HBsAg concentration were measured for all patients. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups， further pairwise comparison using Bonferroni method； the chi-square test was used for comparison of categorical data； a Spearman correlation analysis was used to investigate the degree of correlation between various indicators. ResultsThe positive rate of HBeAg was 18.3%， and among the patients with negative HBV DNA， the patients with positive HBV RNA accounted for 44.1% （86/195）. There was a significant difference in the distribution of the serum levels of HBV RNA， HBV DNA， and HBsAg between the positive HBeAg group and the negative HBeAg group （Z=10.740， 6.300， and 7.280， all P<0.05）. There was a significant difference in the distribution of DNA level between the untreated group and the treatment duration ≤1 year group （P<0.05）； there was a significant difference in the distribution of HBV RNA and HBV DNA levels between the untreated group and the treatment duration >1 year group （P<0.05）； there was a significant difference in the distribution of HBV RNA， HBV DNA， and HBsAg levels between the treatment duration ≤1 year group and the treatment duration >1 year group （P<0.05）. The correlation analysis between the duration of antiviral therapy and the levels of HBV RNA， HBV DNA， and HBsAg showed that the duration of antiviral therapy had an extremely weak negative correlation with the levels of HBV RNA and HBsAg （r=-0.247 and -0.138， both P<0.05） and a strong negative correlation with the level of HBV DNA （r=-0.771， P<0.001）. There was a low degree of correlation between the serum level of HBV RNA and the serum levels of HBV DNA and HBsAg （r=0.360 and 0.442， both P<0.001）. Further stratified analysis showed that in the untreated group， there was a strong positive correlation between HBV RNA and HBV DNA （r=0.752， P<0.001） and a moderate positive correlation between HBV RNA and HBsAg （r=0.559， P<0.001）； in the treatment duration ≤1 year group， there was a low degree of positive correlation between HBV RNA and HBV DNA/HBsAg （r=0.396 and r=0.388， both P<0.001）； in the treatment duration >1 year group， there was a low degree of positive correlation between HBV RNA and HBsAg （r=0.352， P<0.001）. ConclusionSerum HBV RNA is negatively correlated with the duration of treatment with NAs， and the correlation of HBV RNA with HBV DNA and HBsAg gradually decreases with the increase in the duration of treatment. Therefore， it can be used as a supplementary indicator for monitoring the level of virologic response in CHB patients to a certain extent， with a relatively high accuracy in reflecting the level of viral replication in untreated patients.

Corneal refractive surgery, a widely adopted method for correcting refractive errors, has demonstrated its safety, efficacy, and predictability in extensive research. Studies indicate varying degrees of intraoperative fluctuations inintraocular pressure, potentially impacting the posterior segment structures and functions due to surgical techniques, equipment, technical proficiency, and patient-specific factors. Although short-term postoperative follow-up in most patients does not reveal visual dysfunction, the long-term effects and potential risks of transient high intraocular pressure during surgery on the posterior segment structures and functions remain unclear. Therefore, the assessment of posterior segment complications following corneal refractive surgery is of paramount importance in clinical practice. This review aims to explore the characteristics of intraocular pressure fluctuations during corneal refractive surgery and their effects on structures and functions of the vitreous, retina, and optic nerve in the posterior segment, analyze possible causes and risk factors, discuss their implications for current clinical treatment, and consider future trends, providing insights for clinical practice.

Objective To investigate the relationship between insomnia,gastrointestinal symptoms,and glycosylated hemoglobin(HbA1c)levels in individuals diagnosed with type 2 diabetes mellitus(T2DM),as well as the related influencing factors.Methods A total of 910 T2DM patients treated in our multicenter from January 2022 to December 2022 were enrolled in this study.General information(gender,age,smoking and drinking history,exercise,course of disease,treatment and complications),HbA1c,Athens Insomnia Scale(AIS)scores and Gastrointestinal Symptoms Rating Scale(GSRS)scores of patients were collected.The differences of sleep and gastrointestinal symptoms between groups were analyzed,and the correlation between the differences and HbA1c was analyzed.Furthermore,the risk factors for non-standard HbA1c were analyzed.Results The AIS score and GSRS score in the HbA1c control group were less than those in the non-standard group(P＜0.01).Insomnia was reported by 37.0％of T2DM patients,and the HbA1c level in the insomnia group was significantly higher than that in the non-insomnia group(10.00％±2.38％vs.8.26％±1.73％,P＜0.01).Gastrointestinal symptoms were present in 57.5％of T2DM patients,and the HbA1c levels in the group with gastrointestinal symptoms were significantly higher than those in the group without gastrointestinal symptoms(9.26％±2.23％vs.8.43％±1.98％,P＜0.01).Furthermore,26.3％of T2DM patients experienced both insomnia and gastrointestinal symptoms.Remarkably,the HbA1c levels in the group with both insomnia and gastrointestinal symptoms were significantly higher than those in the group without either condition(10.18％±2.44％vs.8.45％±1.86％,P＜0.01).Correlation analysis demonstrated a significant association between sleep quality,gastrointestinal function,and HbA1c levels(P＜0.01).The logistic regression analysis result revealed that age,GSRS score,AIS score,and the presence of insomnia combined with gastrointestinal symptoms were independent risk factors for predicting HbA1c≥6.5％(P＜0.01).Having both insomnia and gastrointestinal symptoms concurrently was the strongest risk factor for substandard HbA1c control,and the risk of blood sugar control may increase about 5 times when both appear together.Conclusion Insomnia and gastrointestinal symptoms are common comorbidities in T2DM patients,showing a cross-interfering relationship,and they appear together with poor blood sugar control,interact causally,and amplify each other.

Polymyxin B, which is a last-line antibiotic for extensively drug-resistant Gram-negative bacterial infections, became available in China in Dec. 2017. As dose adjustments are based solely on clinical experience of risk toxicity, treatment failure, and emergence of resistance, there is an urgent clinical need to perform therapeutic drug monitoring (TDM) to optimize the use of polymyxin B. It is thus necessary to standardize operating procedures to ensure the accuracy of TDM and provide evidence for their rational use. We report a consensus on TDM guidelines for polymyxin B, as endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society. The consensus panel was composed of clinicians, pharmacists, and microbiologists from different provinces in China and Australia who made recommendations regarding target concentrations, sample collection, reporting, and explanation of TDM results. The guidelines provide the first-ever consensus on conducting TDM of polymyxin B, and are intended to guide optimal clinical use.

Objective:To study on the effect of ultrasound-guided thoracic paravertebral nerve (TPVB) block on quality of recovery from general anesthesia in tuberculosis patients with fiberboard exfoliation in post anesthesia recovery unit (PACU).Methods:From May 2018 to December 2019, 40 tuberculosis patients in Changsha Central Hospital with pulmonary fibreboard exfoliation and focal abscess lesions cleaning were randomly divided into two groups, with 20 patients in each group. The patients in group A received endobronchial general anesthesia and in group B received ultrasound-guided TPVB combined with endobronchial general anesthesia. Patients in the two groups were maintained under anesthesia by propofol, and the bispectral index (BIS) was maintained within the range of 40-50. The dosage of propofol and sufentanil was adjusted according to changes in BIS and hemodynamics. The mean arterial pressure (MAP), heart rate (HR) in two groups of patients were recorded at before anesthesia induction (T 0), before cutting leather (T 1), cut skin after (T 2), the end of operation (T 3), extubation time (T 4), and T 5 (time of leaving PACU). The visual analogue scale (VAS) of all patients in resting and cough state was recorded at 5, 30 min after extubation and the time of leaving PACU. The dosage of propofol and sufentanil in the operation and the additional dosage of sufentanil in PACU were recorded in both two groups. And the respiratory recovery time, consciousness recovery time, extubation time and sedation agitation scale(SAS) were observed. The adverse reactions such as nausea, vomiting, drowsiness and hypotension were observed in PACU. Results:Compared with group A, MAP and HR of patients at T 2, T 3, T 4, T 5 in group B were more stable during anesthesia, and VAS of patients in group B were lower than that in group A at each time point after extubation ( P<0.05). The dosage of sufentanil and propofol in group B were (35.92±8.12)μg and (749.56±95.30)mg respectively, which were significantly lower than those in group A [(45.74±4.42)μg and (862.83±105.34)mg, P<0.05]; the dosage of sufentanil in postoperative anesthesia recovery room of group B was (5.26±2.10)μg, significantly less than that of group A (10.35±5.86)μg ( P<0.05). The respiratory recovery time, consciousness recovery time and extubation time in group B were (12.92±5.12) min, (20.56±5.10) min and (26.87 ± 6.16) min, which were shorter than those in group A [(15.74±4.72)min, (25.83±5.34)min and (35.35±5.80)min, P<0.05]. The incidence of postoperative nausea, vomiting, lethargy and hypotension in group B were 10%, 10%, 35% and 20%, which were significantly lower than those in group A (30%, 20%, 75% and 45%, P<0.05). Conclusions:Ultrasound-guided paravertebral nerve block may significantly reduce the dosage of opioid analgesics for general anesthesia in tuberculosis patients with fiberboard exfoliation, accelerate the speed of anesthesia recovery, reduce the agitation during recovery, and improve the quality of anesthesia recovery.
