Objective To compare and analyze the impact of intraocular higher-order aberrations and total ocular higher-order aberrations on visual quality after the implantation of different types of multifocal intraocular lenses(MIOL),in order to provide personalized MIOL selection recommendations for patients.Methods A total of 107 patients(107 eyes)with age-related cataract were selected and divided into the SBL-3,MF15,ZMB00,and Zeiss809 groups based on the type of MIOL implanted.Uncorrected distance visual acuity(UCDVA),best-corrected distance visual acuity(BCDVA),best-corrected near visual acuity(BCNVA),optical parameters and wavefront aberrations were compared 3 months postop-eratively.Results Preoperatively,there were no statistically significant differences in any optical parameters or visual acuity among the four groups(all P＞0.05).At three months postoperatively,there were no significant differences in UCD-VA,BCDVA,BCNVA,corneal aberration,or intraocular spherical aberration among the four groups(all P＞0.05).How-ever,significant differences were observed in the predicted visual acuity at 100％,20％,and 9％contrast(100％VA,20％VA,9％VA),streller ratio(SR),modulation transfer function cutoff frequency(MTF cutoff),intraocular coma,intraocu-lar trefoil,total higher-order aberrations,and the average modulation transfer function height values(MTF AH)of the en-tire eye across various spatial frequencies showed significant differences(all P＜0.05).Pairwise comparisons showed that the ZMB00 and Zeiss809 groups had significantly better 100％VA,20％VA,9％VA,SR,MTF cutoff,and MTF AH,and sig-nificantly lower intraocular coma,intraocular trefoil,and total higher-order aberrations than the SBL-3 group(all P＜0.05).The MF15 group only had significantly lower intraocular trefoil than the SBL-3 group(P＜0.05).Correlation analy-sis results at 3 months postoperatively showed that in the SBL-3 and MF15 groups,UCDVA(logMAR)was positively corre-lated with the objective scattering index and negatively correlated with 100％VA,20％VA,9％VA,SR,and MTF cutoff(all P＜0.05).MTF AH was negatively correlated with intraocular coma and total higher-order aberrations,and positively cor-related with intraocular spherical aberration(all P＜0.05).In the ZMB00 and Zeiss809 groups,MTF AH was negatively cor-related with intraocular coma,intraocular trefoil,and total higher-order aberrations(all P＜0.05),but showed no correla-tion with intraocular spherical aberration(all P＞0.05).Conclusion There are no differences in UCDVA,BCDVA,or BCNVA among patients implanted with the four types of MIOLs,but differences existed in objective visual quality.The ob-jective visual quality of ZMB00 and Zeiss809 is significantly better than that of SBL-3,making them the preferred choices for patients with high-quality visual demands;SBL-3 is suitable for basic demand scenarios;MF15,which is only superior to SBL-3 in terms of intraocular trefoil,can be a compromise option for those sensitive to trefoil aberration.

We aimed to investigate the relationship of dietary zinc intake with new-onset hypertension among Chinese adults. A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey were included. Dietary intake was assessed by three consecutive 24-h dietary recalls combined with a household food inventory. Participants with systolic blood pressure ≽ 140 mmHg or diastolic blood pressure ≽ 90 mmHg or diagnosed by a physician or under antihypertensive treatment during the follow-up were defined as having new-onset hypertension. During a median follow-up duration of 6.1 years, 4269 participants developed new-onset hypertension. Overall, the association between dietary zinc intake and new-onset hypertension followed a J-shape (P for non-linearity < 0.001). The risk of new-onset hypertension significantly decreased with the increment of dietary zinc intake (per mg/day: hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.88-0.98) in participants with zinc intake < 10.9 mg/day, and increased with the increment of zinc intake (per mg/day: HR 1.14; 95% CI 1.11-1.16) in participants with zinc intake ≽ 10.9 mg/day. In conclusion, there was a J-shaped association between dietary zinc intake and new-onset hypertension in general Chinese adults, with an inflection point at about 10.9 mg/day.

Tsutsugamushi disease is an acute infectious disease caused by Rickettsia. Occasionally it has been reported in Macau, China. Critical cases are rare. Because the clinical manifestations of tsutsugamushi disease are non-specific and diverse, if not diagnosed and treated in time, the disease may progress to multiple organ dysfunction syndrome (MODS), severe acute respiratory distress syndrome (ARDS), and even death. A patient with tsutsugamushi disease complicated by MODS was admitted to the intensive care unit (ICU) of Kiang Wu Hospital in Macau, China on September 30, 2021. Combined with the history of outdoor activities (exposure to chigger mite larvae), clinical symptoms and signs (characteristic eschar of tsutsugamushi disease was found on the abdominal skin), related laboratory examinations (Weil-Felix test: negative). Diagnosis of tsutsugamushi disease with MODS. After admission, the patient was treated by anti-infection, correction of coagulation dysfunction, tracheal intubation and mechanical ventilation, noradrenalin to maintain blood pressure, continuous renal replacement therapy (CRRT), but the condition didn't improve significantly. We initiated veno-venous ECMO (VV-ECMO), which was initially setted blood flow to 5 L/min (70 mL·kg -1·min -1), rotate speed to 3 500 rpm, fractional concentration of inspired oxygen (FiO 2) to 1.00. Heparin was used as anticoagulant and activated coagulation time (ACT) was kept between 180 and 200 seconds. Meanwhile the speed of fluid removal in CRRT was adjusted. After 9 hours of ECMO support, the oxygenation improved, the blood flow of ECMO was reduced to about 4 L/min (58 mL·kg -1·min -1), rotate speed to 3 000 rpm. The patient's condition improved after 4 days of ECMO treatment and her ECMO flow rate and FiO 2 could be decreased gradually. On hospital day 5, ECMO was removed. Eight days on mechanical ventilation, the patient was successfully weaned and extubated. On day 11 of hospitalization, weaned the CRRT and turned to intermittent hemodialysis. The patient was transferred out of ICU due to her stable condition on the 12th day hospitalization. After that, her spontaneous urine output increased gradually. The functions of various organs returned to normal. After 36 days of hospitalization, she recovered and was discharged.

Objective: To develop a model for rapid and non-destructive determination of amoxilcillin sodium and sulbactam sodium for injection using the analysis of near infrared diffuse reflectance spectroscopy (NIR) and chemometrics.Methods: Totally 41 batches of commercial samples and 20 batches of laboratory samples were analyzed by NIR and the legal methods.The first derivative and vector normalization were selected as the preprocessing methods and 8 720-5 446 cm-1 was selected as the frequency range.Results: The quantitative model was constructed based on 16 batches of commercial samples and 15 batches of laboratory samples (0.75 g) and the content ranged from 4.45% to 61.82% for amoxilcillin and 15.75% to 30.25% for sulbactam.The root mean square errors of cross validation (RMSECV), determination coefficients (R 2) and root mean square errors of prediction (RMSEP) respectively was 0.858 , 0.998 1 and 0.936 for amoxilcillin, and respectively was 0.541 , 0.988 1 and 0.423 for sulbactam.The model was tested based on 5 batches of commercial samples and 5 batches of laboratory samples (0.75 g) and the results well met with those of the legal methods with difference ≤ 1.5 %.The model also applied in 10 batches of commercial samples (1.5 g) and 2 batches of samples from the other manufacturers.Conclusion: The non-destructive quantitative NIR methods are accurate with good reproducibility, and applicable for the rapid analysis of amoxilcillin sodium and sulbactam sodium for injection.

In clinical practice, the masticatory muscles problems are often encountered occlusion. Masticatory muscles, as a component of the masticatory system, play an important role in occlusion. Both of them interact with each other through neural system. However, there is not enough knowledge about it. This article introduces the function, functional disorder and functional diagnosis of masticatory muscles, and makes a brief analysis of the relation between occlusion and masticatory muscles.

Objective To explore the effect of terazosin hydrochloride combined with finasteride on serum TNF-αand PSA in old patients with benign prostatic hyperplasia.Methods 64 elderly patients of benign prostatic hyperplasia were randomly divided into 2 groups, 32 cases in each group.2 groups were given routine treatment and symptomatic treatment, the control group was given finasteride; the experimental group were treated with terazosin hydrochloride combined with finasteride.A cycle of 2 groups were 28 d, a total of 1 cycle of treatment.Clinical efficacy, maximum urinary flow rate, prostate volume, residual urine volume, international prostate symptom score(IPSS), serum tumor necrosis factor alpha, prostate specific antigen level and adverse reactions were compared after the end of treatment.Results Compared with before treatment, maximum urinary flow rate (Qmax) level of 2 groups increased, prostate volume, residual urine volume, international prostate symptom score(IPSS)decreased (P<0.05), compared with the control group, maximum urinary flow rate of the experimental group was higher (P<0.05), prostate volume, residual urine volume, IPSS were lower (P<0.05), 2 groups of TNF-αand PSA levels decreased after treatment (P<0.05), compared with the control group, TNF-αand PSA levels were lower(P<0.05).There was no significant difference in adverse reactions in 2 groups.Conclusion Terazosin hydrochloride combined with finasteride had a clinical efficacy of elderly patients with benign prostatic hyperplasia, can reduce serum TNF-αand PSA levels.
