ABSTRACT

Objective To study the differences in the blood cell analysis of male officers and soldiers be-tween in the high altitude area station and low altitude area station in summer.Methods A total of 239 male officers and soldiers in the high altitude area(Amdo Xizang,average altitude 4 800 m)and 336 male officers and soldiers in the low altitude area(Nanjing,Jiangsu,average altitude 30 m)from July 18 to 24,2022 were selected as the study subjects and the differences in blood cell analysis parameters of male officers and soldiers stationed between at high altitude and low altitude areas were retrospectively analyzed.Results The eosino-phils percentage(EDS%),eosinophils count(EOS)in the high altitude group were significantly lower than thosein the low altitude group(P<0.05),and the basophillic granulocyte percentage(BASO%),basophillic granulo-cyte count(BASO)and monocyte percentage(MONO%)were significantly higher than those in the low alti-tude group,and the differences were statistically significant(P<0.05),but which in the both groups were in the normal reference ranges.The red blood cell count(RBC)hemoglobin(Hb)and hematocrit(HCT)in the high altitude group were significantly higher than those in the low altitude group(P<0.05),moreover Hb and HCT in the high altitude group were in the upper limit of the medical reference range.The mean corpus-cular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and red blood cell distribution width-standard diviation(RDW-SD)in the high altitude group were lower than those in the low-altitude group(P<0.05),but the both groups were in the normal reference ran-ges;there was no statistically significant difference in the erythrocyte distribution width coefficient of variation(RDW-CV)between the two groups(P>0.05).The platelet(PLT)and thrombocytocrit(PCT)in the high altitude group were higher than those in the low altitude group,the platelet distribution width(PDW),mean platelet volume(MPV)and platelet large cell ratio(P-LCR)were lower than those in the low altitude group,and the differences were statistically significant(P<0.05);PDW in the low-altitude group was at the upper limit of the medical reference range,and the other platelet-related indexes were in the normal range.Conclusion There are obvious differences in the blood cell analysis indicators of male officers and soldiers be-tween the high altitude area and low altitude area.

ABSTRACT

Objective:To investigate the efficacy of endoscopic histoacryl injection in cirrhotic patients with newly-developed esophagogastric varices (EGV) who have previously undergone splenectomy combined with pericardial devascularization.Methods:From January 2015 to January 2020, 125 cirrhotic patients with EGV treated with endoscopic histoacryl injection at the Department of Gastroenterology, Jinling Hospital, Medical School of Nanjing University, were included in the retrospective analysis. There were 45 patients in the group of splenectomy combined with pericardial devascularization (splenectomy group for short) and 80 patients in the non-splenectomy group. The efficacy of endoscopic treatment, postoperative variceal improvement, rebleeding rate, and complications were analyzed between the two groups.Results:Endoscopic histoacryl injection was successfully completed in all 125 patients, and the median volume of histoacryl was 4.5 mL. The overall effective rate in splenectomy and non-splenectomy group was 80.0% (36/45) and 57.5% (46/80), respectively. The difference in the number of significantly effective, effective, and ineffective cases between the two groups was statistically significant (16, 20, 9 cases, and 20, 26, 34 cases, respectively, χ 2=6.469, P=0.039). Two and 14 patients developed rebleeding in the splenectomy group and non-splenectomy group, respectively; and the difference in the rebleeding rate between the two groups was statistically significant (4.4% VS 17.5%, Log-rank P=0.039). No patient died within 1 year in either group, and no serious complications such as ectopic embolism occurred. Conclusion:After splenectomy combined with pericardial devascularization in cirrhotic patients with EGV and hypersplenism, the application of histoacryl has better short-term efficacy and can significantly reduce the rebleeding rate compared with the non-splenectomy group.

ABSTRACT

@#Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.

ABSTRACT

<p><b>PURPOSE</b>To determine the effect of the posterior condylar offset (PCO) on clinical results after total knee arthroplasty (TKA) using a high-flex posterior-stabilized (PS) fixed-bearing prosthesis.</p><p><b>METHODS</b>We prospectively studied the clinical and radiographic materials of 89 consecutive female patients (89 knees), who had undergone primary TKAs for end-stage osteoarthritis. All operations were performed by a single senior surgeon or under his supervision using the same operative technique. Based on the corrected PCO change, we divided all cases into two groups: group A (corrected PCO change ≥0 mm, 58 knees) and group B (corrected PCO change<0 mm, 31 knees). One-year postoperatively, clinical and radiographic variables from the two groups were compared by independent t-test. The associations between the corrected PCO changes and the improvements of clinical variables in all patients were analyzed by Pearson linear correlation.</p><p><b>RESULTS</b>One-year postoperatively, the Knee Society Scores, the Western Ontario and McMaster Universities Osteoarthritis Index, non-weight-bearing active and passive range of knee flexion, flexion contracture, extensor lag, and their improvements had no statistical differences between the two groups (all p>0.05). The corrected PCO change was not significantly correlated with the improvement of any clinical variable (all p>0.05). Group A demonstrated greater flexion than group B during active weight bearing (p<0.05).</p><p><b>CONCLUSIONS</b>Restoration of PCO plays an important role in the optimization of active knee flexion during weight-bearing conditions after posterior-stabilized TKA, while it has no benefit to non-weight-bearing knee flexion or any other clinical result.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the risk factors of postoperative complications in gastric carcinoma patients complicated with liver cirrhosis.</p><p><b>METHODS</b>A retrospective research of 41 gastric cancer patients with liver cirrhosis who underwent surgical therapy was performed. The multivariate Logistic regression analysis was carried out to determine risk factors of postoperative complications.</p><p><b>RESULTS</b>There were no postoperative death in this cohort. Twenty-seven(65.9%) patients developed postoperative complications. As determined by the Logistic regression analysis, Child-Pugh score(OR=27.96, 95% CI:1.16-672.23), albumin level(OR=17.98, 95% CI:1.28-253.36) and intraoperative blood loss(OR=10.60, 95% CI:1.21-92.82) were independent risk factors of postoperative complications.</p><p><b>CONCLUSION</b>As for gastric cancer patients with liver cirrhosis, positive perioperative management, adjustment of Child-Pugh classifications score, following damage control principle during operation and reducing the intraoperative bleeding may decrease the morbidity of postoperative complications.</p>

ABSTRACT

Glucose was transported by the large number of hexose transporters in yeast cells. There were 18 hexose transporter genes had been identified in Saccharomyces cerevisiae. However,as an excellent expression system,there was no information of these genes had been reported in Pichia pastoris. Based on high homologous recombination efficiency in yeast,we chose G418 resistance for screening,200 bp were cloned from the up and down sequences of HXT1 ORF respectively,then ligated to the 5′ and 3′ end of G418 resis-tance gene for recombination. After electroporation of GS115 spheroplast and screened through different G418 concentration plates,finally we obtained one HXT1 gene deletion mutant named GS115?HXT1. The growth rate and glucose consumption of this mutant were both lower than the wide type.
