【Objective】 To analyze the efficacy and safety of intralesional triamcinolone acetonide in the treatment of mass granulomatous mastitis (GLM). 【Methods】 Retrospective analysis was made on 67 patients with GLM who were treated in Xijing Hospital from July 2021 to May 2022 and met the inclusion criteria. Among them, 31 patients were treated with local injection of triamcinolone acetonide, while 36 ones were treated with oral methylprednisolone. All the included patients underwent surgical treatment after their condition met the surgical criteria, and the follow-up period lasted for up to six months after surgery. The two groups were compared in improvement of symptoms and signs, treatment time, clinical effectiveness and safety, and recurrence rate. 【Results】 The effective rate of triamcinolone acetonide group and methylprednisolone group was 100%, but the clinical cure rate was significantly higher in triamcinolone acetonide group than in methylprednisolone group in stratified analysis (P<0.05). The improvement time of symptoms and signs in triamcinolone acetonide group was significantly shorter than that in methylprednisolone group (P<0.05). The incidence of side effects in triamcinolone acetonide group was also significantly reduced compared to methylprednisolone group (P<0.05). Follow-up for half a year showed no recurrence in both groups. 【Conclusion】 Compared with the traditional oral methylprednisolone group, local injection of triamcinolone acetonide in the treatment of mass granulomatous mastitis can rapidly relieve clinical symptoms and signs, shorten treatment time, and has higher efficiency and fewer side effects. Local injection of hormone combined with surgery is effective in treating mass granulomatous mastitis with low recurrence rate.

On February 2022, WHO released the evidence-based guideline on control and elimination of human schistosomiasis, with aims to guide the elimination of schistosomiasis as a public health problem in disease-endemic countries by 2030 and promote the interruption of schistosomiasis transmission across the world. Based on the One Health concept, six evidence-based recommendations were proposed in this guideline. This article aims to analyze the feasibility of key aspects of this guideline in Chinese national schistosomiasis control program and illustrate the significance to guide the future actions for Chinese national schistosomiasis control program. Currently, the One Health concept has been embodied in the Chinese national schistosomiasis control program. Based on this new WHO guideline, the following recommendations are proposed for the national schistosomiasis control program of China: (1) improving the systematic framework building, facilitating the agreement of the cross-sectoral consensus, and building a high-level leadership group; (2) optimizing the current human and livestock treatments in the national schistosomiasis control program of China; (3) developing highly sensitive and specific diagnostics and the framework for verifying elimination of schistosomiasis; (4) accelerating the progress towards elimination of schistosomiasis and other parasitic diseases through integrating the national control programs for other parasitic diseases.

OBJECTIVE: To predict the trends for fine-scale spread of Oncomelania hupensis based on supervised machine learning models in Shanghai Municipality, so as to provide insights into precision O. hupensis snail control. METHODS: Based on 2016 O. hupensis snail survey data in Shanghai Municipality and climatic, geographical, vegetation and socioeconomic data relating to O. hupensis snail distribution, seven supervised machine learning models were created to predict the risk of snail spread in Shanghai, including decision tree, random forest, generalized boosted model, support vector machine, naive Bayes, k-nearest neighbor and C5.0. The performance of seven models for predicting snail spread was evaluated with the area under the receiver operating characteristic curve (AUC), F1-score and accuracy, and optimal models were selected to identify the environmental variables affecting snail spread and predict the areas at risk of snail spread in Shanghai Municipality. RESULTS: Seven supervised machine learning models were successfully created to predict the risk of snail spread in Shanghai Municipality, and random forest (AUC = 0.901, F1-score = 0.840, ACC = 0.797) and generalized boosted model (AUC= 0.889, F1-score = 0.869, ACC = 0.835) showed higher predictive performance than other models. Random forest analysis showed that the three most important climatic variables contributing to snail spread in Shanghai included aridity (11.87%), ≥ 0 °C annual accumulated temperature (10.19%), moisture index (10.18%) and average annual precipitation (9.86%), the two most important vegetation variables included the vegetation index of the first quarter (8.30%) and vegetation index of the second quarter (7.69%). Snails were more likely to spread at aridity of < 0.87, ≥ 0 °C annual accumulated temperature of 5 550 to 5 675 °C, moisture index of > 39% and average annual precipitation of > 1 180 mm, and with the vegetation index of the first quarter of > 0.4 and the vegetation index of the first quarter of > 0.6. According to the water resource developments and township administrative maps, the areas at risk of snail spread were mainly predicted in 10 townships/subdistricts, covering the Xipian, Dongpian and Tainan sections of southern Shanghai. CONCLUSIONS Supervised machine learning models are effective to predict the risk of fine-scale O. hupensis snail spread and identify the environmental determinants relating to snail spread. The areas at risk of O. hupensis snail spread are mainly located in southwestern Songjiang District, northwestern Jinshan District and southeastern Qingpu District of Shanghai Municipality.

Objective The purpose of this study was to identify a pathogenic variant in a Chinese family with Alport syndrome and analyze the pathogenicity of the variant. Methods Using targeted region capture and high-throughput sequencing technology, we identified the genetic variant of the proband with Alport syndrome, verified the variant in the family members by Sanger sequencing, and analyzed its influence on the pre-mRNA splicing process by in vitro minigene assay. Results A heterozygous variant c.2767G>T (p.Gly923Cys) was identified as a novel variant in exon 32 of the COL4A5 gene in the proband, which was confirmed by Sanger sequencing to be cosegregated with disease in the family. The minigene assay demonstrated that the c.2767G>T variant induced deletion of exon 32 of the COL4A5 gene. Conclusion A novel COL4A5 mutation was identified by targeted region capture and high-throughput sequencing, which has enriched the gene mutation spectrum of Alport syndrome. The exonic mutation c.2767G>T confirmed to be a splicing mutation by in vitro minigene assay, which may lead to a deeper insight into the molecular pathogenesis of Alport syndrome.

Objective To evaluate the effects on Stroke Volume Variation (SVV) during ventilation with selective lobar collapse (SLC) and one-lung ventilation (OLV) in thoracoscopic operation. Methods 60 patients scheduled for thoracoscopic operation to treat lower thoracic esophageal cancer or cardial carcinoma were randomly assigned into two groups: patients in one lung ventilation (OLV) group received right lung ventilation and left lung collapses, patients in selective lobar collapse (SLC) group received right lung and superior lobe of left lung ventilation by the use of endobronchial blocker. The intraoperative blood oxygen saturation (SpO2) and end-tidal carbon dioxide tension (PETCO2) were maintained in normal range. Record SVV, cardiac output (CO), stroke volume (SV), systolic blood pressure (SBP), diastolic blood pressure (DBP), the heart rate (HR), cardiac index (CI) at four time points: 10 min after two lung ventilation in supine position (T1), 10 min after two lung ventilation in lateral position (T2), OLV or SLC for 10 min after the pleura was opened (T3), two lung ventilation for 10 min before the pleura was closed (T4). Results There was no statistically significant difference between the two groups (P > 0.05). Comparison between groups: There was no significant difference between the patients in OLV group and SLC group, including HR, SBP, DBP, CO, CI, SV and SVV (P > 0.05). Comparison in the group: SBP and DBP in OLV group and SLC group were significantly higher than T1at T3(P < 0.05). The SVV of OLV group and SLC group was significantly reduced at T3and T4(P < 0.05). Conclusion There was no significant difference in SVV monitoring of Vigileo monitoring with OLV and SLC in thoracoscopic operation. SVV can be used to monitor blood volume state during ventilation by SLC.

AIM:To analyze the imageological changes of acute and chronic central serous chorioretinopathy (CSC) by 2 types of optical coherence tomography (OCT). METHODS:A retrospective analysis was performed, inclu-ding data of 60 eyes from 56 patients with CSC diagnosed by conventional eye examination, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA), which were divided into acute group (28 eyes of 28 patients) and chronic group (32 eyes of 28 patients) according to imageological examinations and duration (6 months). Optical coher-ence tomography angiography (OCTA) and spectral domain optical coherence tomography ( SD-OCT) were performed to study the vessel density of the chorioretinal leyers and the integrity of the outer retinal structure. RESULTS:In the pa-tients with chronic CSC, OCTA in 4 eyes ( 12.50% ) revealed the presence of a distinct choroidal neovascularization (CNV), while no evidence of CNV in ICGA was observed. However, no sign of CNV in acute CSC group both on OCTA and ICGA was found. The occurrence of 'dark areas' in chronic CSC was much higher than that in acute CSC ( P <0.01). In addition, the integrity of the outer retinal structure (defined as tissue between external limiting membrane and retinal pigment epithelium) in acute group was significantly better than that in chronic group ( P <0.01). CONCLU-SION:Our study demonstrates the existing secondary CNV that is not demonstrated by ICGA in the chronic CSC patients, and the different characteristics of retinochoroid structures between acute and chronic CSC in OCTA and SD-OCT are ob- served. Chronic CSC has more severe structural changes.

Objective To acquire cerebral blood flow (CBF) in patients with severe intracranial atherosclerotic stenosis with enhanced pseudo-continuous arterial spin labeling (e-pCASL) and compare it with the findings of dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC PWI) and pseudo-continuous arterial spin labeling (pCASL). Methods A total of 39 consecutive patients with severe intracranial atherosclerotic stenosis were enrolled in this study. All these patients underwent e-pCASL, pCASL, and DSC PWI. Blood supply territory of the stenosed artery was outlined as region of interest (ROI) and a mirror ROI was applied. Ratios of CBF were calculated as value of ROI/value of mirror ROI. SNK variance analysis was conducted to compare the CBF values of three persufion methods. Factorial analysis of variance and Pearson were employed to analysis the difference and the correlation of e-pCASL CBF ratio, pCASL CBF ratio, and DSC PWI relative cerebral blood flow(rCBF) ratio. Results The e-pCASL CBF ratio, pCASL CBF ratio, and DSC PWI rCBF ratio were not significantly different (P=0.476). TTP showed the CBF ratios were not significantly different between the healthy side and diseased side in patients with severe intracranial atherosclerotic stenosis. ATT showed the correlations of pCASL CBF ratio and DSC PWI rCBF ratio were not affected by ATT. Conclusions e-pCASL with multiple-post labeling delay time and pCASL have good consistency with DSC PWI in the quantitative measurement of hypoperfusion pattern. As an accurate, simple, non-invasive, and repeatable technique, e-pCASL has good correlation with DSC PWI in the quantitative measurement of hypoperfusion pattern that is not affected by ATT.

OBJECTIVETo study the relationship between the patatin-like phospholipase domain-containing protein 3 (PNPLA3) gene and hereditary susceptibility to non-alcoholic fatty liver disease (NAFLD) by detecting single nucleotide polymorphisms (SNPs).

METHODSPeripheral blood DNA from 315 patients diagnosed with NAFLD (including the spectrum of simple steatosis (SS) and non-alcoholic steatosis (NASH)) and 336 control subjects was used to determine the PNPLA3 genotype by polymerase chain reaction (PCR) and direct sequencing. The relationship of SNPs and NAFLD-related markers of liver function were assessed by correlation analysis.

RESULTSThe SNP rs738409 was identified in more of the NAFLD patients (allele variant frequencies: NAFLD, 65.40%; NASH: 71.87%; SS, 56.47%) than in the controls (33.18%). Case-control analysis revealed that carriers of the 148GG genotype were at 3.81-fold (95% CI: 3.03 ~ 4.79) higher risk of developing NAFLD and at 1.97-fold (95% CI: 1.41 ~ 2.75) higher risk of progressing from SS to NASH, compared with non-carriers. rs738409 was also found to be associated with serum levels of alanine aminotransferase (ALT) and y-glutamyltransferase (y-GT) (both P less than 0.05). Carriers of the 148GG genotype had significantly higher body mass index, ALT, and fasting insulin than carriers of the 148CC genotype (all P less than 0.05), and significantly higher level of serum HDL than carriers of either the 148CC genotype or the 148GC genotype (both P less than 0.05).

CONCLUSIONPolymorphisms in the PNPLA3 gene may play an important role in mediating susceptibility to developing NAFLD in the Chinese population. The rs738409 polymorphism, in particular, is related to development and progression of NAFLD and may play a role in the contribution of PNPLA3 to NAFLD pathogenesis.
