Objective:To investigate the regulation of acupuncture on γ-interferon (INF-γ) and tumor necrosis factor (TNF) of lung cancer-operative cases. Methods: to determine the INF-γ and TNF contents in the blood serum of lung cancer patients by double antibody sandwich immuno-enzymatic method (ELISA); to measure the INF-γ and TNF contents of 30 lung cancer patients in the acupuncture anesthesia group and 30 lung cancer patients in general anesthesia group before the operation and at the 8th days, the 12th day after the operation respectively and make comparison between the two groups. Results:The pre-operation INF-γ contents of the two groups showed no significant difference (P＞0.05); the post-operation INF-γ contents of the two groups showed significant difference at 8th day and 12th day after the operation (P＜0.05); the acupuncture anesthesia group was superior to the general anesthesia group; the self-comparison of the anesthesia group showed significant difference at the 12th day and 8th day after the operation (P＜0.05); the pre-operation TNF contents of the two groups showed no significant difference (P＞0.05) and the post-operation TNF contents of the two groups showed significant difference at the 8th day and 12th day after the operation (P＜0.05). Conclusion:Acupuncture can increase the serum INF-γ and TNF contents of lung cancer patients and therefore regulate the immunity of the patients.

Perianal fistulizing Crohn' s disease (pfCD) is the commonly seen perianal disease in Crohn's disease (CD), and its main treatment is the combined use of medical and surgical therapy on basis of radiological assessment. However, low response rate and high recurrence rate are found in clinical practice. It is of great importance to predict the therapeutic efficacy accurately according to the individual characteristics of patients for improving the prognosis of pfCD. This article reviewed the progress of research on factors related to the therapeutic efficacy of pfCD for helping to develop more specifically targeted treatment strategies.

Objective To investigate whether simple visual assessment of FVERVOT(the right ventricular outflow tract Doppler flow velocity envelop) graphs aids in hemodynamic differentiation. Method The hemodynamics, echocardiography, and clinical data of 88 patients with pulmonary hypertension (PH) were reviewed. The FVERVOTgraphs were categorized into normal pattern (no notch; NN), late systolic notch pattern (LSN) or mid-systolic notch pattern (MSN). Results The pulmonary vascular resistance (PVR) was highest in the MSN pattern (9.2±3.5 WU; P＜0. 001), in comparison with LSN (5,7 ±3. 1 WU) and NN (3.3±2.4 WU) patterns. The ratio of stroke volume to pulse pressure (compliance) also varied with different patterns of FVERVOr graph (MSN = 1.2 ± 0. 5; LSN = 1.7 ± 0.8; NN = 2.6 ± 1. 7, P = 0.001 and 0.04 respectively compared with NN). The specificity and sensitivity of MSN were 96% and 71%, respectively in case of a PVR ＞ 5 WU (PPV 98%). In the patients with PH, any notching pattern of FVERVOT graph was highly associated with PVR ＞ 3 WU (OR = 22.3, 95 % CI: 5.2 ～ 96.4), whereas the NN pattern predicted a PVR ≤3 WU and pulmonary artery wedge pressure (PAWP) ＞ 15 mmHg (OR =30.2, 95%CI: 6.3 ～ 144.9). Conclusions Visual inspection of the shape of the FVERVOT graphs provides insight into the hemodynamic status of patients with PH.

Objective:To observe the imaging features of fundus lesions associated with COVID-19.Methods:A observational case series study. Twenty eyes of 10 patients with fundus lesions associated with COVID-19 at Xiamen Eye Center of Xiamen University from December 10, 2022 to January 20, 2023 were included in this study. There were 1 males and 9 females, aged from 17 to 49 years, with the median age of 26 years. The time of ocular symptoms after the diagnosis of COVID-19 was 0-2 days. The time from the onset of ocular symptoms to seeing a doctor was 1-14 days. All patients were examined by best-corrected visual acuity (BCVA), intraocular pressure, color fundus photography, infra-red fundus photography (IR), optical coherence tomography (OCT). Serum D-dimer examination was performed in 3 patients. The median BCVA was 0.4. There was no abnormalities in intraocular pressure and anterior segment examination. Among 20 eyes of 10 patients, there were 10 eyes of 5 patients with acute macular neuroretinopathy (AMN), 6 eyes of 3 patients with Purtscher-like retinopathy (PLR), 4 eyes of 2 patients with central retinal vein occlusion (CRVO). The imaging features of fundus were observed and analyzed.Results:Retinal lesions included AMN, paramacular central medial retinopathy (PAMM), PLR, cotton wool spots, hemorrhage, optic disc edema, macular edema. AMN was found in 10 eyes, with reddish-brown and wedge-shaped lesion in the fovea, dark area in IR and hyper reflectivity in outer nuclear layer and outer plexiform layer by OCT. The cotton wool spot showed hyper reflectivity on retinal nerve fiber layer whereas PAMM showed band-shape hyper reflectivity in inner nuclear layer by OCT. The Purtscher spot was seen at the posterior pole and/or peripapillary in 6 eyes of PLR. By OCT examination, the retinal nerve fiber layer corresponding to Purtscher flecken was significantly thickened and the reflex was enhanced. Among 6 eyes of PLR, there were 4 eyes combined with AMN, 1 eye with PAMM and macular edema. In 4 eyes of CRVO, vitreous cells, optic disc edema, retinal flame, spot hemorrhage, and atypical cotton wool spots were seen in 2 eyes.Conclusions:The manifestations of fundus lesions associated with COVID-19 are varied. The multilayer structure of retina is involved, and the microvessels of retina and choroidal capillary layer are damaged.

Objective To investigate the significance of plasma levels of insulin-like growth factor(IGF)-1 and insulin-like growth factor binding protein(IGFBP)-3 in predicting acute respiratory distress syndrome(ARDS)and prognosis in critical patients.Methods A totally of 131 critical patients in intensive care unit(ICU)of the First Affiliated Hospital of Wenzhou Medical University were reviewed.Plasma concentrations of IGF-1,IGFBP-3,blood biochemistry,procalcitonin(PCT),lactic acid(LAC)and blood albumin were measured in enrolled patients.The 60-day fatality of enrolled patients was calculated.The differences between ARDS group and control group,as well as 60-day dead group and survival group were compared.Results Plasma IGF-1 and IGFBP-3 in ARDS group were significantly lower than those in control group,while plasma PCT was higher than that in control group.Plasma levels of IGF-1 and IGFBP-3 in dead group were significantly lower than those in survival group.Multivariate Logistic regression analysis and receiver operating characteristic curve results showed that IGF-1 area under curve(AUC)was 0.770,sequential organ failure assessment(SOFA)(AUC=0.692)and PCT(AUC=0.710)were independent risk factors for ARDS in critical patients.IGF-1(AUC=0.807),IGFBP-3(AUC=0.759)and SOFA score(AUC=0.859)were independent risk factors for death in critical patients.Conclusion The plasma levels of IGF-1 and IGFBP-3 in critica patients are significantly decreased,which may be an important factor for ARDS risk and fatality in critical patients.

Objective:To investigate the genetic etiology of fetal conotruncal heart defects (CTDs) and to evaluate the performance of copy number variation sequencing (CNV-seq) and whole exome sequencing (WES) in identifying the genetic etiology.Methods:This retrospective study involved 196 fetuses diagnosed with CTDs by fetal echocardiography in Beijing Anzhen Hospital, Capital Medical University from June 2017 to December 2021. CNV-seq was performed to screen for chromosomal abnormalities [aneuploidy and copy number variations (CNVs)] in the fetuses and their parents, and then WES was performed if CNV-seq was negative. The diagnostic yields of genetic abnormalities [aneuploidy+CNVs+single nucleotide variations (SNVs)] for different types of CTDs were compared using Chi-square test. Results:CNV-seq revealed 54 cases (27.6%, 54/196) with chromosomal abnormalities, including 14 (7.1%, 14/196) aneuploidies, 39 (19.9%, 39/196) CNVs and one aneuploidy complicated by CNVs. Together with another 13 fetuses with pathogenic or likely pathogenic SNVs detected by WES among the rest 142 cases whose CNV-seq results were negative, the total detection rate of genetic abnormalities was 34.2% (67/196). WES increased the diagnostic yield for CTDs by 9.2% (13/142). There was significant difference in the diagnostic yields for different types of CTDs ( χ2=20.31, P=0.002). The diagnostic yield was relatively high for interrupted aortic arch of type B, absent of the pulmonary valve -type of tetralogy of Fallot (9/10 and 8/12), but low for transposition of the great arteries (12.5%, 5/40). Conclusions:CNVs are the common genetic abnormalities in fetal CTDs, and SNVs are also detected in some cases. It is recommended that all fetuses with CTDs should undergo genetic testing. CNV-seq should be used in combination with WES if possible to improve the identification of genetic etiology and provide reference for genetic counseling.

ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition， physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ，and the prevalence of overweight and obesity was 36.75% and 17.19%， respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 （OR=1.333， 95%CI： 1.030‒1.724）， intake of first-generation antipsychotics （OR=1.413， 95%CI： 1.112‒1.796）， intake of second-generation antipsychotics （OR=1.573， 95%CI： 1.288‒1.921）， high-normal blood pressure （OR=1.549， 95%CI： 1.245‒1.927）， high-abnormal blood pressure （OR=2.824， 95%CI： 2.204‒3.619）， elevated ALT （OR=1.874， 95%CI： 1.386‒2.535）， elevated FBG （OR=1.270， 95%CI： 1.066‒1.513）， and elevated TG （OR=1.652， 95%CI： 1.335‒2.044） were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60， taking first-generation and second-generation antipsychotics， blood pressure higher than 120/80 mmHg， elevated ALT， elevated FBG， and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance， medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.

In order to search for new anti-inflammatory agents with strong activity and less toxicity relative to CDDO-Me, the ester prodrugs 2-8 of CDDO-Me were synthesized by treatment of oleanolic acid(OA)with DMF/K2CO3 to generate 1, followed by esterification of 1 with various aliphatic and aromatic carboxylic acids, respectively. All the target compounds showed strong inhibitory effects on LPS-induced NO production in RAW 264. 7 cells. Among them, compounds 2 and 7 possessed the most potent inhibitory effects with IC50=(2. 34±0. 67)and(3. 83±0. 97)nmol/L, respectively. Moreover, MTT assay indicated that all the target compounds(2-8)displayed much weaker anti-proliferative activity against RAW 264. 7 cell lines than CDDO-Me, suggesting that they may be less toxic than CDDO-Me.
