ABSTRACT
Objective The long-term epidemiological and etiological characteristics of hand, foot and mouth disease (HFMD) in Huai’an, Jiangsu were analyzed to provide scientific evidence for the prevention of HFMD. Methods The data of HFMD reports, etiological diagnosis and in Huai’an from 2009 to 2022 were described and analyzed. Results A total of 78 535 cases were reported from 2009 to 2022 , with 14-year average annual incidence rate of 114.71/100 000. Before 2020, the incidence rate of HFMD in Huai’an showed the epidemic intensity increased every other year on the whole, and the average annual incidence rate during the COVID-19 pandemic (2020-2022) (55.69/100 000) was significantly lower than that in previous years (2009-2019) (129.95/100 000). The joinpoint regression analysis showed that the best fitting model from 2009 to 2022 had no joinpoints, APC=AAPC=-1.24%. The overall trend showed a monotonously decreasing trend, but the trend was not statistically significant. The male-to-female distribution ratio was 1.53:1, and the age distribution was mainly under 5 years old, especially in scattered children. The epidemic season was from April to July. The results of etiological surveillance showed that the co-epidemic of Coxsackievirus A16 (CV-A16) and Enterovirus A71 (EV-A71) during the early stages had changed to the co-epidemic of CV-A16 and CV-A6 in the current period. Conclusion The burden of HFMD in Huai’an was large, and the epidemic intensity increased every other year was affected by the COVID-19 pandemic. The epidemiological features after the COVID-19 pandemic should be further monitored.

ABSTRACT
In recent years, many studies have found that vaginal microbiota is closely related to female reproductive tract diseases. However, traditional microbial culture technology has the defects of long culture cycle and most microorganisms cannot be cultured. The development of metagenomics technique has broken the limitations of culture technology, and has been gradually applied to the study of vaginal microorganisms with the characteristics of high throughput, short time, identification of microbial population structure and gene function. It also provides technical support for elucidating the relationship between vaginal microbiota and female reproductive tract diseases. This article mainly introduces the metagenomics techniques and their applications in prevention, screening and diagnosis of common female reproductive tract diseases, and discusses their promising development and limitations to be overcome.

Dihydrofolate reductase (DHFR), a housekeeping enzyme in primary metabolism, has been extensively studied as a model of acid-base catalysis and a clinic drug target. Herein, we investigated the enzymology of a DHFR-like protein SacH in safracin (SAC) biosynthesis, which reductively inactivates hemiaminal pharmacophore-containing biosynthetic intermediates and antibiotics for self-resistance. Furthermore, based on the crystal structure of SacH-NADPH-SAC-A ternary complexes and mutagenesis, we proposed a catalytic mechanism that is distinct from the previously characterized short-chain dehydrogenases/reductases-mediated inactivation of hemiaminal pharmacophore. These findings expand the functions of DHFR family proteins, reveal that the common reaction can be catalyzed by distinct family of enzymes, and imply the possibility for the discovery of novel antibiotics with hemiaminal pharmacophore.
ABSTRACT
Objective:To analyze the risk factors of carbapenem-resistant Klebsiella pneumoniae(CRKP)infection in tumor patients. Methods:The clinical data of hospitalized tumor patients with Klebsiella pneumoniae(KP)infection admitted in Hangzhou Cancer Hospital during January 2021 to December 2022 were retrospectively analyzed. Patients were divided into CRKP group( n=37)and carbapenem-sensitive Klebsiella pneumoniae(CSKP)group( n=142)according to drug sensitivity. The risk factors of CRKP infection were analyzed by univariate and multivariate Logistic regression. Results:Univariate analysis showed that cardiovascular disease( χ2=4.554, P=0.033),carbapenem use ≥7 days( χ2=53.483, P<0.001)and hospital stay >7 days( χ2=3.871, P=0.049)were significantly associated with CRKP infection in tumor patients. Multivariate Logistic analysis showed that carbapenem therapy for ≥7 days( OR=18.280,95% CI 6.533-51.147, P<0.001)was an independent risk factor for CRKP infection in tumor patients. Conclusion:Tumor patients with long-term use of carbapenems are prone to CRKP infection.
ABSTRACT
In acute lung injury, two subsets of lung macrophages exist in the alveoli: tissue-resident alveolar macrophages (AMs) and monocyte-derived alveolar macrophages (MDMs).However, it is unclear whether these 2 subsets of macrophages have different functions and characteristics during the recovery phase. RNA-sequencing of AMs and MDMs from the recovery period of LPS-induced lung injury mice revealed their differences in proliferation, cell death, phagocytosis, inflammation and tissue repair. Using flow cytometry, we found that AMs showed a higher ability to proliferate, whereas MDMs expressed a larger amount of cell death. We also compared the ability of phagocytosing apoptotic cells and activating adaptive immunity and found that AMs have a stronger ability to phagocytose, while MDMs are the cells that activate lymphocytes during the resolving phase. By testing surface markers, we found that MDMs were more prone to the M1 phenotype, but expressed a higher level of pro-repairing genes. Finally, analysis of a publicly available set of single-cell RNA-sequencing data on bronchoalveolar lavage cells from patients with SARS-CoV-2 infection validated the double-sided role of MDMs. Blockade of inflammatory MDM recruitment using CCR2 −/− mice effectively attenuates lung injury. Therefore, AMs and MDMs exhibited large differences during recovery. AMs are long-lived M2-like tissue-resident macrophages that have a strong ability to proliferate and phagocytose. MDMs are a paradoxical group of macrophages that promote the repair of tissue damage despite being strongly pro-inflammatory early in infection, and they may undergo cell death as inflammation fades. Preventing the massive recruitment of inflammatory MDMs or promoting their transition to pro-repairing phenotype may be a new direction for the treatment of acute lung injury.
ABSTRACT
Objective To investigate the clinical significance of thrombospondin type 1 domain-containing 7A (THSD7A) and neural epidermal growth factor-like 1 protein (NELL1) in phospholipase A2 receptor (PLA2R)-negative membranous nephropathy (MN). Methods A total of 116 PLA2R-negative MN patients treated in Hangzhou TCM Hospital Affiliated to Zhejiang Chinese Medical University from 2014 to 2021 were enrolled in this study.Immunohistochemistry was employed to detect THSD7A and NELL1 in the renal tissue.The pathological characteristics,treatment,and prognosis were compared between positive and negative groups. Results The 116 PLA2R-negative MN patients included 23 THSD7A-positive patients and 9 NELL1-positive patients.One patient was tested positive for both proteins.The THSD7A-positive group showed higher positive rate of IgG4 (P=0.010),more obvious glomerular basement membrane (GBM) thickening (P=0.034),and higher proportion of stage Ⅱ MN and lower proportion of stage I MN (P=0.002) than the THSD7A-negative group.The NELL1-positive group had lower positive rates of C1q and IgG2 (P=0.029,P=0.001),less obvious GBM thickening (P<0.001),more extensive inflammatory cell infiltration (P=0.033),lower proportion of deposits on multi-locations (P=0.001),and lower proportion of atypical MN (P=0.010) than the NELL1-negative group.One patient with THSD7A-positive MN was diagnosed with colon cancer,while none of the NELL1-positive patients had malignancy.Survival analysis suggested that THSD7A-positive MN had worse composite remission (either complete remission or partial remission) of nephrotic syndrome than the negative group (P=0.016),whereas NELL1-positive MN exhibited better composite remission of nephrotic syndrome than the negative group (P=0.015).The MN patients only positive for NELL1 showed better composite remission of nephrotic syndrome than the MN patients only positive for THSD7A (P<0.001). Conclusions THSD7A- and NELL1-positive MN is more likely to be primary MN,and there is no significant malignancy indication.However,it might have a predictive value for the prognosis of MN.

Objective:To investigate the construction of containing CT imaging features Nomograms model of postoperative intraluminal thromus (ILT) formation in patients with aortic dissective aneurysm (ADA).Methods:One hundred and twenty patients with Stanford type B ADA treated with overlapping stent endoluminal repair and multilayer spiral CT (MSCT) examination in Affiliated Hospital of Jining Medical College from May 2020 to February 2022 were selected. The patients were divided into the modeling population (84 patients) and the validation population (36 patients) according to a 7∶3 ratio. The factors influencing postoperative ILT formation in ADA patients were analyzed by univariate and Logistic multifactor regression models, and the prediction model of postoperative ILT formation was constructed based on the influencing factors.Results:In the modeled population, the rate of ILT formation within 1 month after luminal repair with overlapping stents was 27.38%(23/84), including 5 cases in the aortic arch and 18 cases in the abdominal aorta. In the modeled population, the results of univariate analysis showed that the sex, age, body mass index(BMI), smoking, drinking, hypertension, hyperlipidemia, rupture diameter, rupture distance from left subclavicular artery, involvement of important branches, uneven thickening of aneurysm wall, low density on plain scan and operation timing between the ILT formation group and non-ILT formation group had no statistically significant ( P>0.05). The diabetes mellitus, irregular inner wall, calcified plaque, postoperative anticoagulant therapy, B-type brain natriuretic peptide (BNP), fibrinogen (Fib), D-dimer (D-D) and C-reactive protein (CRP) between the two groups had statistical differences: 43.48%(10/23) vs. 11.48%(7/61), 86.96%(20/23) vs. 57.38%(35/61), 91.30%(21/23) vs. 62.30%(38/61), 21.74%(5/23) vs. 57.38%(35/61), (523.60 ± 128.74) ng/L vs.(271.83 ± 109.65) ng/L, (3.82 ± 0.96) g/L vs. (2.85 ± 0.83) g/L, (601.37 ± 75.62) μg/L vs. (389.20 ± 68.79)μg/L, (0.63 ± 0.19) mg/L vs. (0.48 ± 0.15) mg/L, P<0.05. The results of Logistic multifactor regression analysis showed that diabetes mellitus, irregular inner wall, calcified plaque, postoperative anticoagulant therapy and BNP, Fib, D-D CRP levels were influential factors for postoperative ILT formation in Stanford type B ADA patients ( P<0.05). The C-index of the model was 0.903 and 0.894 for the modeled and validated populations, respectively, which had good discrimination and was good at predicting ILT formation after operation in Stanford type B ADA patients. The model had good clinical utility in predicting postoperative ILT formation in Stanford B ADA patients. Conclusions:The Nomograms model can help to screen and identify patients with high risk of ILT formation at an early clinical stage.
ABSTRACT
@#The prediction of compound-protein interaction (CPI) is a critical technological tool for discovering lead compounds and drug repurposing during the process of drug development.In recent years, deep learning has been widely used in CPI research, which has accelerated the development of CPI prediction in drug discovery.This review focuses on feature-based CPI prediction models.First, we described the datasets, as well as typical feature representation methods commonly used for compounds and proteins in CPI prediction.Based on the critical problems in modeling, we discussed models for CPI prediction from two perspectives: multimodal features and attention mechanisms.Then, the performance of 12 selected models was evaluated on 3 benchmark datasets for both classification and regression tasks.Finally, the review summarizes the existing challenges in this field and prospects for future directions.We believe that this investigation will provide some reference and insight for further research on CPI prediction.
ABSTRACT
With high incidence, high disability rate and serious impact on patients' quality of life, advanced primary angle-closure glaucoma (PACG) with cataract is a severe eye disease in China and its main treatment method is surgery.Phacoemulsification cataract extraction and intraocular lens implantation (PEI) combined with trabeculectomy has been used to treat advanced PACG with cataract, but there are many postoperative complications.Recently, combined PEI, goniosynechialysis (GSL) and goniotomy (GT) has been proven to be a safe and effective surgical treatment for advanced PACG with cataract.At present, the combined PEI+ GSL+ GT surgery has been widely applied, but there is still a lack of uniform standards for its clinical application.Therefore, it is necessary to formulate a detailed and complete recommendation of the surgical procedures for PEI+ GSL+ GT, to standardize its application in clinical practice.Based on the analysis of the existing problems, some glaucoma experts in China have formulated detailed and complete operation norms, as well as expert recommendations on surgical indications and contraindications, anesthetic methods, surgical techniques and perioperative medication to standardize the application process of PEI+ GSL+ GT in clinical practice.
ABSTRACT
Minimally invasive glaucoma surgery (MIGS) has been successfully incorporated in clinical practice in recent years.Increasing evidence shows that MIGS also plays an increasingly important role in the treatment of primary angle-closure glaucoma (PACG). Surgical peripheral iridectomy (SPI) plus goniosynechialysis (GSL) and goniotomy (GT), as a new procedure, has been proven to be safe and effective in the treatment of PACG with no or mild cataracts.However, there is still a lack of uniform standards for indications, surgical procedures, and perioperative medication.Therefore, it is necessary to formulate a detailed and complete expert recommendations on surgical procedures to standardize the application of combined SPI+ GSL+ GT in the treatment.Some experts in glaucoma treatment and management in China have discussed the current problems and developing trend in MIGS for PACG and put forward the expert recommendations of standard process, including indications, anaesthetic methods, surgical site, operating procedure and rational administration of drugs in perioperation, in order to standardize the medical process of clinicians using combined SPI+ GSL+ GT in PACG treatment and lay a foundation for better evaluation of the efficacy of MIGS.
ABSTRACT
Objective:To evaluate the preliminary effectiveness and safety of surgical peripheral iridectomy (SPI) combined with goniosynechilysis (GSL) and goniotomy (GT) in the treatment of advanced primary angle-closure glaucoma (PACG).Methods:A multicenter observational case series study was performed.Thirty-five eyes of 27 patients with advanced PACG, who underwent SPI+ GSL+ GT with a follow-up of at least 6 months, were included from August 2021 to January 2022 at Zhongshan Ophthalmic Center, Handan City Eye Hospital, Shijiazhuang People's Hospital, West China Hospital of Sichuan University, and the Third Affiliated Hospital of Chongqing Medical University.The mean follow-up time was 9(7, 10) months.Pre- and post-operative best corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured with an ETDRS chart and a Goldmann applanation tonometer, respectively.The number of anti-glaucoma medications applied before and after surgery was recorded, and the complications after surgery were analyzed.Success rate of surgery was calculated.Complete surgical success was defined as an IOP of 5-18 mmHg (1 mmHg=0.133 kPa) and 20% reduction from baseline without anti-glaucoma medication or reoperation.Qualified success was defined as achieving criterion of complete success under anti-glaucoma medications.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2021KYPJ177). Written informed consent was obtained from each subject.Results:The mean preoperative IOP was (30.83±8.87)mmHg, which was significantly decreased to (15.69±3.70)mmHg at 6 months after the surgery ( t=8.588, P<0.001), with a 44.00% (34.78%, 60.00%) decline of 13.00(8.00, 21.00)mmHg.The median number of anti-glaucoma medications was significantly reduced from 2(0, 3) preoperatively to 0 (0, 1) postoperatively ( Z=-3.659, P<0.001). The mean preoperative and postoperative 6-month BCVA were 0.80(0.63, 1.00) and 0.80(0.60, 1.00), respectively, showing no significant difference ( Z=-0.283, P=0.777). Complete surgical success rate was 62.86%(22/35), and the qualified success rate was 91.43%(32/35). Surgical complications mainly included hyphema (6/35), IOP spike (3/35), and shallow anterior chamber (4/35). There was no vision-threatening complication. Conclusions:SPI+ GSL+ GT is preliminarily effective and safe in the treatment of advanced PACG, which provides a new option for PACG.
ABSTRACT
Minimally invasive glaucoma surgery (MIGS) has been successfully incorporated in clinical practice in recent years.Increasing evidence shows that it also plays an important role in the treatment of primary angle-closure glaucoma (PACG). Goniosynechialysis (GSL) is a key surgical procedure used by MIGS for PACG, which involves separating the peripheral anterior synechia and reopening the angle.However, there is still a lack of uniform standards for indications and surgical procedures.Therefore, it is necessary to formulate a detailed and complete expert consensus on surgical procedures to standardize the application of clinicians in the treatment.
ABSTRACT
Objective:To analyze the risk factors for heart failure in patients with hemodialysis, and to construct a nomogram model.Methods:The clinical data of 218 patients with hemodialysis in Xianyang Central Hospital from January 2021 to April 2022 were retrospectively analyzed. Among them, 83 cases developed heart failure (heart failure group), and 135 cases did not develop heart failure (control group). The relevant clinical data were recorded, including age, sex, body mass index, disease duration, concurrent infection, blood calcium, blood phosphorus, soluble CD 146 (sCD 146), soluble growth-stimulated expression gene 2 protein (sST2), N-terminal brain natriuretic peptide precursor (NT-proBNP), time-averaged urea concentration (TACurea), tumor necrosis factor α (TNF-α), blood creatinine and 24 h urine volume. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of each index in predicting heart failure in patients with hemodialysis. Multivariate Logistic regression was used to analyze the independent risk factors of heart failure in patients with hemodialysis. R language software 4.0 "rms" package was used to construct the nomogram model for predicting the heart failure in patients with hemodialysis, the calibration curve was internally validated, and the decision curve was used to evaluate the predictive efficacy of the nomogram model. Results:There were no statistical difference in gender composition, age, body mass index, disease duration, 24 h urine volume and blood creatinine between the two groups ( P>0.05); the rate of concurrent infection, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea in heart failure group were significantly higher than those in control group: 39.76% (33/83) vs. 8.89% (12/135), (1.53 ± 0.34) mmol/L vs. (1.27 ± 0.24) mmol/L, (43.60 ± 10.24) μmol/L vs. (28.08 ± 7.99) μmol/L, (49.00 ± 9.41) μg/L vs. (34.53 ± 8.05) μg/L, (38.57 ± 6.79) μg/L vs. (29.72 ± 5.64) μg/L, (5.18 ± 0.92) μg/L vs. (4.07 ± 1.13) μg/L and (24.28 ± 4.37) mmol/L vs. (17.96 ± 2.52) mmol/L, the blood calcium was significantly lower than that in control group: (1.95 ± 0.36) mmol/L vs. (2.31 ± 0.39) mmol/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the optimal cut-off values of blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea for heart failure in patients with hemodialysis were 2.01 mmol/L, 1.42 mmol/L, 34.15 μmol/L, 40.37 μg/L, 35.37 μg/L, 4.33 μg/L and 20.74 mmol/L. Multivariate Logistic regression analysis result showed that the blood calcium (≤2.01 mmol/L), blood phosphorus (>1.42 mmol/L), sCD 146 (>34.15 μmol/L), sST2 (>40.37 μg/L), NT-proBNP (>35.37 μg/L), TNF-α (>4.33 μg/L) and TACurea (>20.74 mmol/L) were independent risk factors for heart failure in patients with hemodialysis ( OR = 1.183, 1.582, 1.915, 1.105, 1.459, 1.347 and 1.717; 95% CI 1.102 to 1.191, 1.274 to 1.868, 1.716 to 2.105, 1.072 to 1.141, 1.225 to 1.703, 1.132 to 1.574 and 1.482 to 1.935; P<0.05 or <0.01). The blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea were used as predictors to construct a nomogram model for predicting heart failure in patients with hemodialysis. Internal validation result showed that the nomogram model predicted the heart failure with good concordance in patients with hemodialysis (C-index = 0.811, 95% CI 0.675 to 0.948); the nomogram model predicted the heart failure in patients with hemodialysis at a threshold>0.18, provided a net clinical benefit, and all had higher clinical net benefits than blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea. Conclusions:The nomogram model constructed based on blood calcium, blood phosphorus, sCD 146, sST2, NT-proBNP, TNF-α and TACurea has better clinical value in predicting the heart failure in patients with hemodialysis.
ABSTRACT
Objective:To investigate the change of D-Dimer (D-D), cardiac troponin I (cTnI) and vasoactive-inotropic score (VIS) after Stanford type A aortic dissection (TAAD) and thier predictive effect on death outcome.Methods:120 patients with TAAD who were treated in the Affiliated Hospital of Jining Medical College from January 2019 to January 2022 were retrospectively selected and divided into death group ( n=17) and survival group ( n=103) according to the 28-day survival after operation. The difference of clinical data between the two groups was compared, and the influencing factors of postoperative death in TAAD patients were analyzed by logistic regression method. Results:The age, deep hypothermic circulatory arrest time, D-D and cTnI of the patients in the death group were (60.50±5.42)years old, (30.40±9.92)min, (15.65±5.52)g/L and (3.32±0.82)mg/L, respectively, which were significantly higher than those in the survival group (all P<0.05). The VIS score and change of VIS score in the death group at 24 hours after operation were (9.66±1.10)points and (4.50±0.91)points respectively, which were significantly higher than those in the survival group (all P<0.05). Logistic regression analysis showed that age, D-D, cTnI and change of VIS score were the influencing factors of death after TAAD (all P<0.05). The area under the receiver operating characteristic (ROC) curve predicted by the D-D, cTnI and change of VIS score for death in TAAD patients was 0.718, 0.691 and 0.789 respectively (all P<0.05). Conclusions:Postoperative death of TAAD patients is affected by their age, D-D, cTnI and change of VIS score. The D-D, cTnI and change of VIS score have certain application value in predicting postoperative death of patients.
ABSTRACT
Objective:To evaluate the effectiveness of esketamine during perioperative anesthesia for acute and chronic pain after cesarean section.Methods:One hundred and fifty patients scheduled for elective cesarean section under spinal anesthesia were randomly assigned into 2 equal groups ( n=75) using a random number table: esketamine group (group E) and control group (group C). Subarachnoid block was administered with 9-11 mg of hyperbaric bupivacaine with 0.33% glucose concentration. After the delivery of the fetus, 0.15 mg/kg (1 mg/ml) esketamine was pumped intravenously for 30 min in the group E, while the same dosage of normal saline was administered in the group C. Furthermore, patients received an intravenous patient controlled intravenous analgesia (PCIA) pump after surgery (100 μg sufentanil + 1.25 mg/kg esketamine + 8 mg ondansetron for the group E, 100 μg sufentanil + 8 mg ondansetron for the group C). Heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were recorded in the initial time of esketamine administration, and 5, 15 min, and 30 min after administration. The pain Numerical Rating Scale (NRS) score at rest and during coughing were recorded at 2, 6, 12, 24 h and 48 h after surgery. The first analgesic time and cumulative sufentanil consumption were recorded at 0-12 h, 12-24 h, 24-48 h, 0-24 h and 0-48 h after surgery. Moreover, we recorded the incidence of chronic pain at 3 and 6 months after surgery. Results:There were no significant differences in HR, SBP and DBP between the two groups immediately after administration of esketamine and 5, 15 min and 30 min after administration (all P>0.05). At rest or during coughing, the pain NRS score were significantly lower at 2, 6 h, and 12 h postoperatively in group E compared to group C (all P<0.05). The time to first analgesia in group E was significantly longer than the group C [(176.8±18.3)min vs (148.5±16.9)min, P<0.05]. The cumulative sufentanil consumption was significantly lower in group E during 0-12 h, 12-24 h, 0-24 h and 0-48 h postoperatively than in group C (all P<0.05), but there was no statistical significance between the two groups at 24-48 h ( P>0.05). There were no significant difference between the two groups in the incidence of chronic pain at 3 months and 6 months after surgery ( all P>0.05). The incidence of chronic pain in group E was lower than that in group C at 3 months [13.4%(9/67) vs 18.8%(13/69), P=0.392] and 6 months [10.7%(6/56) vs 16.1%(10/62), P=0.391], but the difference was not statistically significant. Conclusions:Perioperative administration of esketamine provided superior short-term analgesia after cesarean section and did not increase the psychotomimetic adverse event rate. However, the development of chronic pain was not restrained.
ABSTRACT
AIM: To compare the differences and agreement of anterior segment biometric parameters of myopic patients measured by domestic Scansys and the imported Sirius based on the principle of Scheimpflug imaging technique.METHODS: In this case series study, 103 cases(103 eyes)that underwent pre-refractive surgery(including small incision lenticule extraction, femtosecond laser-assisted in situ keratomileusis, transepithelial photorefractive keratectomy and implantable contact lens implantation)at Aier Excellent Eye Hospital from May 2022 to October 2022 were recruited. Preoperative keratometry(Km), central corneal thickness(CCT), anterior chamber depth(ACDEndo.), anterior chamber angle(ACA), anterior chamber volume(ACV), white to white(WTW)of patients were recorded.RESULTS: The results of Km, CCT, ACA, and WTW measured by Scansys and Sirius were 42.88(41.54, 44.60)and 42.98(41.56, 44.52)D,(541.52±29.08)and(549.55±29.62)μm, 42.70°±2.67° and 46.63°±5.13°, 12.10±0.60 and 11.98±0.47 mm, respectively, showing the difference was statistically significant(all P<0.01). The ACV measured by Scansys and Sirius was 194.26±31.06 and 191.47±25.65 mm3, and ACDEndo. was 3.40(3.17, 3.57)and 3.43(3.19, 3.56)mm, with no statistically significant difference(all P>0.05). The range of Km, CCT, ACA, ACDEndo., ACV and WTW values measured by the two instruments was small, with an average difference close to zero, and the points percentage of 95% limits of agreement(LoA)was <5%, which is of good consistency.CONCLUSIONS: Scansys and Sirius have small differences and good agreement in the parameters, which can be replaced by each other in clinical practice. Scansys could theoretically be used to extrapolate the implantable contact lens model or could be a new option for anterior segment parameter measurements.
ABSTRACT
By reviewing ancient materia medica and combining with modern literature, the textual research of Magnoliae Flos has been conducted to verify the name, origin, producing area, harvesting and processing methods, in order to provide basis for the selection and use of this herb in the development of famous classical formulas. After the textual research, it could be seen that the correct name of Magnoliae Flos was Xinyi in the past dynasties, meaning spicy flower buds. The main original plants used in past dynasties are Magnolia denudata and M. biondii. The history of the research on its scientific name in recent times is complicated, many foreign scholars have given several different scientific names, but most of them are inconsistent with the actual situation of Magnoliae Flos used in ancient China, because foreign scholars failed to collect the original plants of Magnoliae Flos for accurate identification. Before the Ming dynasty, Magnoliae Flos was mainly produced in Shaanxi, and then the recorded production areas gradually increased. After the founding of the People's Republic of China, the products produced in Henan named M. biondii were highly respected, and Henan was regarded as authentic producing area, and because of the collection and distribution through Yuzhou, it was customarily called Huichunhua. In ancient times, the harvesting period of Magnoliae Flos mostly concentrated in the first and second months of the lunar calendar, and the flower buds of M. biondii were also recommended to be used as medicine, but nowadays the flower buds are mostly collected in winter and spring, and those with dry buds, large size, yellow-green color, tight inner petals, fragrant smell, and no impurities are preferred. In the past dynasties, raw products were the mainstream, and there were also frying, soaking and so on. Based on the results, it is suggested that the flower buds of M. biondii should be used in the development of famous classical formulas. If the original formula does not specify the processing requirements, the raw products can be used as medicine.
