Objective:To observe the efficacy of intravitreal injection of conbercept (IVC) combined with subthreshold micropulse laser photocoagulation (SMLP) in the treatment of diabetic macular edema (DME).Methods:A randomized controlled trial. From December 2020 to January 2022, 100 patients (100 eyes) with DME diagnosed by examination in Shanxi Aier Eye Hospital were included in the study. The patients were randomly divided into IVC group (50 eyes) and IVC+SMLP group (50 eyes). All the eyes were treated with IVC once a month for 3 times, and the eyes in IVC+SMLP group were treated with SMLP within 2 weeks after IVC. All affected eyes were examined by best corrected visual acuity (BCVA), which was statistically converted to logarithm of the minimum angle of resolution (logMAR) visual acuity. The central macular thickness (CMT) was measured by optical coherence tomography. Before the treatment, the logMAR BCVA of patients in IVC group and IVC+SMLP group were 0.56±0.04 and 0.55±0.03, respectively. The CMT were (437.36±11.35) μm and (434.58±10.88) μm, respectively. There was no significant difference in logMAR BCVA and CMT between the two groups ( t= 0.476, 1.027; P>0.05). The patients were followed up for 12 months after treatment. The times of IVC and the changes of BCVA and CMT were compared between the two groups. Independent sample t-test was used to compare the logMAR BCVA, CMT and times of IVC between groups. Results:After 12 months treatment, the logMAR BCVA of IVC group and IVC+SMLP group were (241.63±29.79) μm and (240.47±30.46) μm, respectively. Compared with those before treatment, 12 months after treatment, the BCVA of the two groups increased significantly ( t=7.014, 5.608; P<0.001), while CMT decreased significantly ( t=8.126, 6.013; P<0.001). There was no significant difference in BCVA and CMT between the two groups ( t=0.835, 0.764; P>0.05). The number of IVC in IVC group and IVC+SMLP group were (8.15±2.04) times and (5.91±1.80) times, respectively, and the difference was statistically significant ( t=5.210, P<0.001). Conclusions:Both IVC+SMLP and IVC alone can effectively reduce CMT and increase BCVA in patients with DME. Combination therapy can reduce the number of IVC.

As one of the important means for saving severely burned patients, mechanical ventilation can not only improve the function of important organs such as heart, lung, and kidney, but also stabilize the homeostasis of the body, thus promoting the recovery of patients. Improper use of mechanical ventilation, however, can lead to many complications, among which the ventilator-induced lung injury (VILI) is one of the most common and serious complications, accompanying with a high mortality rate. The target of preventing VILI is to minimize the risk of lung injury caused by mechanical ventilation. This article reviews the pathogenesis, diagnosis, and early prevention and treatment of VILI caused by mechanical ventilation in burned patients.

Objective To observe the effects of acupuncture therapy with finger on back-shu point on acid reflux and lower esophageal sphincter pressure (LESP) of the patients with gastroesophageal reflux disease (GERD). Methods Totally 120 patients of GERD were randomly divided into treatment group and control group through random number table method, 60 cases in each group. Patients in the treatment group were treated with the acupuncture therapy with finger on back-shu point, and patients in control group were treated with lansoprazole tablets and dispersible mosapride citrate for two weeks. Total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time of two groups were observed six months after the treatment. At the same time, the LESP variation of two groups was followed up six months after the treatment. Results The total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time decreased significantly in all patients after treatment (P<0.01), while the comparison between groups showed no significant difference (P>0.05). After treatment, LESP of two groups was significantly improved (P<0.05) than before treatment. After stopping treatment half a year, the treatment group had obvious difference (P<0.05) compared with before treatment, while the control group had no significant difference (P>0.05). Conclusion The acupuncture therapy with finger on back-shu point can reduce acid reflux, and achieve the goal of treatment of GERD by improving the lower esophageal sphincter pressure. The duration of improving LESP is longer.

Objective:To evaluate the effect of remimazolam pretreatment on brain injury following thalamic hemorrhage in mice.Methods:Sixty clean-grade healthy adult CD1 male mice, weighing 25-30 g, aged 7-8 weeks, were divided into 3 groups ( n=20 each) by using a random number table method: sham operation group (Sham group), brain injury group (BI group) and remimazolam pretreatment group (Rem group). Remimazolam 25 mg/kg was intravenously injected via the tail vein in group Rem.and the equal volume of normal saline was given instead in Sham group and BI group.Ten min later, type Ⅳ collagenase 0.01 U/10 nl was microinjected into unilateral ventroposterolateral nucleus and ventromedial nucleus to develop a mouse model of brain jury induced by thalamic hemorrhage.The rats were sacrificed at 6 h after developing the model, brain tissues were taken for measurement of the wet/dry weight (W/D) ratio, and hippocampal tissues were taken and stained with haematoxylin and eosin for determination of the count of the viable neurons in the hippocampal dentategyrus area, count of apoptotic neurons in the hippocampal CA1 region (by TUNEL), expression of CCAAT/enhancer-binding protein homologous protein (CHOP), activating transcription factor 4 (ATF4) and X-box binding protein-1 (XBP1) mRNA (by real-time polymerase chain reaction) and expression of CHOP, Bcl-2, Bax and caspase-3 (by Western blot) and for microscopic examination of ultrastructure of hippocampal tissues (with a transmission electron microscope). Results:Compared with group Sham, the W/D ratio of brain tissues and count of apoptotic neurons in the hippocampal CA1 area were significantly increased, the count of viable neurons in the hippocampal dentate gyrus was decreased, the expression of CHOP, ATF4 and XBP1 mRNA in hippocampal tissues was up-regulated, the expression of CHOP, caspase-3 and Bcl-2 was up-regulated, and the expression of Bax was down-regulated in BI and Rem groups ( P<0.05). Compared with group BI, the W/D ratio of brain tissues and count of apoptotic neurons in the hippocampal CA1 area were significantly decreased, the number of viable neurons in the hippocampal dentate gyrus was increased, the expression of CHOP, ATF4 and XBP1 mRNA in hippocampal tissues was down-regulated, the expression of CHOP, caspase-3 and Bcl-2 was down-regulated, and the expression of Bax was up-regulated in group Rem ( P<0.05). Conclusion:Remimazolam pretreatment can reduce the brain injury following thalamic hemorrhage in mice, and the mechanism may be related to inhibition of cell apoptosis induced by endoplasmic reticulum stress in hippocampus.

OBJECTIVE: To analyze the clinical features and variants of ABCD1 gene in a Chinese pedigree affected with X-linked adrenoleukodystrophy. METHODS: Clinical data of the proband were collected and analyzed. Potential variant of the ABCD1 gene were analyzed by PCR and Sanger sequencing of the proband, his parents and 100 unrelated healthy individuals. RESULTS: The prominent features of the proband included cerebellar and brainstem lesions, along with increased serum level of very-long chain fatty acids. He was found to harbor a hemizygous c.1509delG (p.L504Sfs*54) variant of the ABCD1 gene, for which his mother was heterozygous. The same variant was not detected in his father and 100 healthy controls. CONCLUSION X-linked adrenoleukodystrophy has a variety of clinical manifestations. Discovery of the c.1509delG (p.L504Sfs*54), as a novel pathogenic variant of the ABCD1 gene, has enabled diagnosis and genetic counseling for this pedigree.

In the face of the worldwide threat of severe acute respiratory syndrome (SARS) to human life, some of the most urgent challenges are to develop fast and accurate analytical methods for early diagnosis of this disease as well as to create a safe anti-viral vaccine for prevention. To these ends, we investigated the antigenicity of the spike protein (S protein), a major structural protein in the SARS-coronavirus (SARS-CoV). Based upon the theoretical analysis for hydrophobicity of the S protein, 18 peptides were synthesized. Using Enzyme-Linked Immunosorbent Assay (ELISA), these peptides were screened in the sera from SARS patients. According to these results, two fragments of the S gene were amplified by PCR and cloned into pET-32a. Both S fragments were expressed in the BL-21 strain and further purified with an affinity chromatography. These recombinant S fragments were confirmed to have positive cross-reactions with SARS sera, either by Western blot or by ELISA. Our results demonstrated that the potential epitope regions were located at Codons 469-882 in the S protein, and one epitope site was located at Codons 599-620. Identification of antigenic regions in the SARS-CoV S protein may be important for the functional studies of this virus or the development of clinical diagnosis.

In Korea and China, ilaprazole is a widely used proton pump inhibitor in the treatment of gastric ulcers. In this study, a specific and sensitive LC-MS/MS method has been developed and validated for the quantification of ilaprazole enantiomers in the rat plasma, using R-lansoprazole as the internal standard. The enantioseparation was achieved on a CHIRALPAK AS-RH column (4.6 mm × 150 mm, i.d. 5μm), with a mobile phase composed of 10 mM ammonium acetate aqueous solution and acetonitrile (60:40, V/V), at a flow-rate of 0.5 mL/min. The method was validated over the concentration range of 0.5-300 ng/mL for both, R- and S -ilaprazole. The lower limit of quantification was 0.5 ng/mL for both enantiomers. The relative standard deviation (RSD) of intra- and inter-day precision of R-ilaprazole and S-ilaprazole was less than 10.9％, and the relative error accuracy (RE) ranged from -0.5％-2.0％. Finally, the method was successfully evaluated in rats in a stereoselective pharmacokinetic study of the ilaprazole racemate.
