Objective To analyse the effects of the lung recruitment manoeuvre(RM)mode implemented by ICU specialist nurses on remission of the patients with acute respiratory distress syndrome(ARDS),with the aim to explore the safety,feasibility and effectiveness of clinical implementation,and to further provide a new mode for patient management in nursing practice.Methods A total of 40 ARDS patients admitted into the ICU from January 2018 to August 2021 were randomly selected and divided into control group and trial group in equal number with a random number table.Patients in the control group was treated with a conventional RM mode implemented by doctors,and the RM mode implemented by the ICU specialist nurses was applied to the patients in trial group.The indexes of arterial blood gas analysis,mechanical ventilation time,length of ICU stay,number of RM,number of adjustments to a RM plan,and complication rate were compared between the two groups after the second RM implementation.Results There was no statistically significant difference in arterial partial pressure of oxygen,arterial partial pressure of carbon dioxide and oxygenation index between the groups at 1h and 24h after the second RM implementation(P>0.05).There was no statistically significant difference in the number of RM,mechanical ventilation and length of ICU stay between the groups(P>0.05).The number of modifications of the RM plan in the trial group was significantly more than that in the control group(P<0.05).There was no complication of RM in both groups.Conclusions The RM mode implemented by ICU specialist nurses could achieve good clinical effects in the treatment of patients with ARDS. The approach is safe and practicable.

OBJECTIVETo investigate the methods of interventional catheterization for combined congenital heart disease and to evaluate its efficacy in children.

METHODSFrom March 1994 to December 2003, 15 cases (6 boys, 9 girls) underwent transcatheter intervention for combined congenital heart diseases. The procedure of transcatheter intervention was as follows: for pulmonary stenosis (PS) and atrial septal defect (ASD) or patent ductus arteriosus (PDA), PBPV first, occlusion of ASD or PDA later; for coarctation of aorta (COA) and PDA, dilation of COA first, occlusion of PDA 4-15 months later; for aortic stenosis (AS) and PDA, PBAV first, occlusion of PDA later; for ventricular septal defect (VSD) and PDA, all occlusions with detachable coils.

RESULTTranscatheter intervention for combined congenital heart diseases was successful in all patients. There was no residual shunt after occlusion immediately apart from 2 cases of PDA which were little residual after occlusion immediately. Follow-up for (3.57 +/-2.61) years, the systolic pressure gradients across pulmonary valve and coarctation were normal by ultrasonic or transcatheter, except AS. There was 3 cases presented postoperative complications: 1 with mechanical haemolysis, 1 with fall off of coil and 1 with arterial embolism, respectively.

CONCLUSIONTranscatheter intervention for combined congenital heart diseases could obtain satisfactory results with appropriate indications and procedure manipulations.

Objective To understand the prevalence of Clonorchis sinensis infection among residents in two communities of Zhongshan City,and evaluate the effect of albendazole treatment,so as to offer the evidence for formulating the strategy of clo-norchiasis prevention and control.Methods The stool specimens were collected from the residents of two comprehensive dem-onstration areas,and the eggs of C.sinensis were detected by Kato-Katz technique.Those who were tested positive were treated with albendazole(0.4,twice a day for 4 days in adults,and half dosage for children aged 16 years or below).Three weeks after the treatment,the stool specimens were recollected and retested to evaluate the effect. Results A total of 532 people were in-vestigated and 96 were tested positive,with an infection rate of 18.05%.The infection rate was 28.63%(69/241)in the males and 9.28%(27/291)in the females,and there was a significant difference between them(Χ2=334.99,P<0.01).The infection rate increased with the increase of the age(Χ2=63.84,P<0.01).Among the 96 positive residents,94 received the albendazole treatment,and 86 were retested after the treatment with a negative conversion rate of 91.86%(79/86).Of the 7 residents without the conversion,5 had irregular medication.No severe adverse reactions were reported during the period of treatment. Conclu-sions The infection rate of C.sinensis among residents in the two communities of Zhongshan City is high,especially among the males and aged people.The effect of albendazole is good in the treatment of C.sinensis infection.In the future,the general sur-vey and treatment should be strengthened in order to lower the infection rate.

OBJECTIVE: To investigate the feasibility and safety of substituting tacrolimus(FK506) for cyclosporin A(CsA) on delaying the pace of renal dysfunction in patients with biopsy-proven chronic allograft nephropathy(CAN). METHODS: Seventy-three renal transplantation patients with CAN proved by allograft biopsy were collected in this study. Patients were randomly divided into 2 groups. Patients were either converted to FK506(FK506 group, n=43) or remained on their initial CsA-based immunosuppression(CsA group, n=30). The clinical data at study entry and after 12 months including blood urea nitrogen(BUN), serum creatinine(SCr), glomerular filtration rate(GFR), 24-hour urine protein excretion, serum total cholesterol(TC), triglyceride(TG), low density lipoprotein(LDL) and the side effects of calcineurin inhibitors were monitored during a follow-up of over 12 months. RESULTS: Twelve months later, the level of SCr was statistically reduced and GFR levels were obviously elevated in the FK506 group as compared with CsA group [(194.8+/-42.5)micromol/L vs. (245.4+/-52.8)micromol/L and (50.14+/-3.92)mL/(min.1.73 m(2)) vs. (40.58+/-2.49)mL/(min.1.73 m2), P<0.01]. Quantity of 24-hour urine protein excretion in the FK506 group was (2.0+/-0.5)g which is significantly lower than (3.9+/-0.7)g in the CsA group(P<0.01). TC, TG, and LDL levels remained unchanged in the CsA group, while those were statistically reduced in the FK506 group respectively [(5.19+/-0.73)mmol/L vs. (6.94+/-1.37)mmol/L, (1.86+/-0.84)mmol/L vs. (3.14+/-1.38)mmol/L, (3.03+/-0.71)mmol/L vs. (3.82+/-0.89)mmol/L, P<0.01]. Tremor obviously increased (P<0.01) and hypertension obviously decreased (P<0.05) in the FK506 group compared with the CsA group. CONCLUSION FK506 treatment can greatly improve the proteinuria and hyperlipidemia. Conversion from CsA to FK506 is an effective and safe alternative therapy for delaying the progression of renal dysfunction induced by CAN.

Objective:To analyze the clinical characteristics of patients with de-novo non-alcoholic fatty liver disease (de-novo NAFLD) and patients with de-novo NAFLD combined with metabolic syndrome (MS) after liver transplantation (LT) , and to determine the related risk factors.Methods:Patients who underwent LT at the Organ Transplantation Center, the Affiliated Hospital of Qingdao University, from Jan. 2016 to Oc. 2020 and were monitored until Oct. 2021 were gathered. The recipients were divided into the group with/without de-novo NAFLD, and LT recipients with de-novo NAFLD were divided into the group with/without combined MS. Clinical characteristics of the LT recipients with de-novo NAFLD combined with MS were analyzed. Logistic regression analyses were performed to identify the risk factors for LT recipients with de-novo NAFLD and those with combined MS.Results:A total of 324 LT recipients with a median follow-up of 2.9 years (range: 2.0-4.3 years) were included in the study. De-novo NAFLD was diagnosed in 21.0% (68/324) of the LT recipients, and MS was diagnosed in 44.1% (30/68) of these patients. Compared with LT recipients without de-novo NAFLD, those with de-novo NAFLD had higher preoperative body mass index (BMI) , blood glucose, glycated hemoglobin levels and lower platelet levels, and longer postoperative follow-up, higher BMI, waist circumference, albumin, triglycerides (TG) , low-density lipoprotein (LDL) , blood glucose, glycated hemoglobin levels, and the incidence of MS (all P<0.05) . Preoperative platelets, glucose, postoperative albumin, LDL and BMI were independent risk factors for predicting de-novo NAFLD after LT (all P<0.05) . Preoperative glucose performed well in predicting the occurrence of de-novo NAFLD (threshold: 5.5mmol/L, P<0.001, AUC=0.678) . The differences in Pre-LT blood glucose, post-LT BMI, waist circumference, prevalence of prediabetes or diabetes, fatty liver index (FLI) , and NAFLD fibrosis score (NFS) between de-novo NAFLD LT recipients with and without combined MS were significantly different (all P<0.05) . Conclusions:The incidence of de-novo NAFLD after LT is noteworthy, and LT recipients with de-novo NAFLD are more likely to have a combination with MS. In preoperative treatment, keeping blood glucose to 5.5 mmol/L or below trends helps to lower the risk of de-novo NAFLD following LT. LT recipients’ nutritional state and lipid levels require prompt care. High albumin levels might not be a desirable thing. De-novo NAFLD LT recipients with concomitant prediabetes or diabetes may imply an increased risk of developing comorbid MS during the post-LT follow-up. Controlling FLI levels in LT recipients with de-novo NAFLD may reduce the risk of developing comorbid MS.

OBJECTIVETo identify the prevalence and risk factors of diabetes and prediabetes in the community residents above 18 years old in the suburbs of Guangzhou.

METHODSBetween April and May in 2008, the residents above 18 years living in 6 communities of Guangzhou for 5 or more years were sampled with multistage clustering sampling. The sampled residents were surveyed by questionnaires, and physical examination and glucose determination were carried out.

RESULTSA total of 1532 residents were sampled. The incidence of diabetes mellitus in these community residents was 8.46%, and that of impaired glucose regulation was 6.59%. Age, body mass index, family history of diabetes mellitus, case history of hypertension, hyperlipidemia, hypertension and smoking were all the independent risk factors for impaired glucose regulation and diabetes mellitus.

CONCLUSIONDiabetes and prediabetes are prevalent in the community residents in Guangzhou. Controlling the risk factors such as obesity, hypertension, lipid metabolism disorder among the residents above 40 years with a family history of diabetes mellitus and hypertension is key to prevention of impaired glucose regulation and diabetes mellitus.

OBJECTIVETo investigate the gene mutations in a pedigree with inherited prothrombin (FII) deficiency.

METHODSThe activated partial thromboplastin time (APTT), prothrombin time (PT), FII activity (FII:C) and FII antigen (FII:Ag) test were used for phenotype diagnosis. The genomic DNA was extracted from the peripheral blood of the propositus. All the 14 exons, intron/exon boundaries and the 5' and 3' untranslated regions (UTR) of the prothrombin gene were amplified by polymerase chain reaction (PCR). The PCR products were screened by direct sequencing and the mutations detected were further confirmed by restricted enzyme digestion. One hundred and three healthy blood donors were used as controls.

RESULTSThe phenotype of the propositus was prothrombin deficiency (type I). With reference to the prothrombin nucleotide sequence published by Degen & Dacie, three variations were found in the FII gene of the propositus. Among them, the novel mutation was a homozygous A601G subtitution in exon 2.

CONCLUSIONThe prothrombin deficiency of the propositus is caused by a homozygous Glu29 to Gly mutation in the prothrombin gene.

Objective: To investigate the current situation of cell phone use and sleep quality among college students, establish a sleep quality trajectory model and explore the influence of cell phone use on the sleep quality trajectory. Methods: Based on data from the College Student Behavior and Health Cohort Study 2019-2020, a latent class growth modeling was used to establish a sleep quality trajectory model among college students. The baseline influencing factors of sleep quality trajectories among college students were analyzed by χ² test, and the effects of cell phone use on sleep quality trajectories were analyzed by binary logistic regression. Results: A total of 1 092 college students were included in the analysis. The detection rates of cell phone use and poor sleep quality were 24.5% and 13.3%. Latent class growth model identified two groups of sleep quality trend trajactories: an improved sleep quality group (86.0%) and a decreased sleep quality group (14.0%). The result of binary logistic regression showed that the cell phone use was a risk factor of sleep quality trajectories. Conclusion: The cell phone use during college period could increase the risk of poor sleep quality. Targeted intervention measures about cell phone use should be adopted to improve the sleep quality among college students.
