[Objective]To evaluate the knowledge,attitude and practice(KAP)of medication use and safety among the patients with acquired immune deficiency syndrome(AIDS)in a 3A-grade hospital of Guangzhou city,and to provide scientific basis for AIDS prevention and treatment.[Methods]A questionnaire survey was conducted among AIDS patients aged 18 years and above in our hospital to investigate their KAP regarding medication use and safety.[Results]A total of 549 questionnaires were collected,of which 503 were valid,with an effective recovery rate of 91.6%.The average scores of KAP were(14.58±8.49),(25.21±6.92)and(47.58±3.33),respectively,with the scoring rates of 36.46%,63.02%,and 95.16%,respectively.There were statistically significant differences(P＜0.05)in knowledge scores among people with different ages,education levels and occupations.Multiple linear regression showed that education level and medical insurance status had most significant impact on knowledge scores(P<0.05).Significant differences were found in attitude scores among people with different education levels(P<0.05),as well as in practice scores among people with different occupations(P<0.05).Multiple linear regression revealed that age,occupation,knowledge score and attitude score had a significant impact on practice scores(P<0.05).Patients expected to receive pharmaceutical care services from the pharmacists via face-to-face communication,network platform and telephone consultation on medication knowledge such as adverse drug reactions and response measures,drug-drug interactions,missed medication and response measures,medication adherence measures,etc.[Conclusions]AIDS patients in this hospital have a good awareness of medication safety,but their knowledge of medication use needs improvement.Some bad habits may affect their compliance,resulting in safety hazards.Therefore,there is an urgent demand for pharmaceutical care services related to rational drug use.

ObjectiveThis paper aims to analyze the current status of outcome indicators in randomized controlled trials （RCT） of traditional Chinese medicine （TCM） for treating chronic atrophic gastritis （CAG）， so as to provide references for constructing the core outcome set （COS） of TCM in the treatment of CAG. MethodChina National Knowledge Infrastructure （CNKI）， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library databases were searched for RCTs of TCM in the treatment of CAG in the last five years. The risk of bias of included studies was evaluated， and the selection status of outcome indicators was statistically analyzed. ResultA total of 150 RCTs were included， with a sample size of 44-398 cases. 164 outcome indicators were reported， with an application frequency of 1 229 times. The outcome indicators were classified into seven indicator domains according to functional attributes， followed by physical and chemical examination （69.41%）， TCM syndrome （12.69%）， symptoms and signs （11.15%）， safety indicators （5.37%）， quality of life （0.65%）， long-term prognosis （0.65%）， and economic evaluation （0.08%）. According to the statistical analysis， there were problems in the selection of outcome indicators in RCTs of TCM for treating CAG， including various indicators， non-standard name reports， unclear primary and secondary indicators， random combination of subjective and objective indicators， neglected patient report outcome indicators， missing long-term prognosis and economic indicators， insufficient reporting of safety indicators， and inconsistent measurement tools and measurement time points. ConclusionIn the past five years， there have been many problems in the selection of outcome indicators in RCTs of TCM for treating CAG. It is necessary to actively promote the construction of the COS of TCM in the treatment of CAG and promote the high-quality development of clinical research of TCM.

Objective To investigate the genetic causes of auditory neuropathy with optic atrophy in a family.Methods The proband's medical history and family history were inquired in detail,and relevant clinical examina-tions were performed to confirm the diagnosis of auditory neuropathy with optic atrophy,and the genetic pedigree of the family was drawn.Peripheral blood of proband(Ⅲ-7)was collected for whole exome sequencing,and the patho-genicity of the detected mutations were interpreted.Blood samples of proband's wife(Ⅲ-8),eldest daughter(Ⅳ-7),second daughter(Ⅳ-9)and son(Ⅳ-10)were tested for mutation sites by Sanger sequencing.Combined with clinical manifestations and examination results,the family was studied.Results The genetic pattern of this family was autosomal dominant.The proband showed decreased visual acuity at the age of 19,bilateral sensorineural deaf-ness at the age of 30,and decreased speech recognition rate.Among 20 members of the family of 5 generations,10(2 deceased)showed similar symptoms of hearing and visual impairment.Proband(Ⅲ-7),eldest daughter(Ⅳ-7)and son(Ⅳ-10)underwent relevant examination.Pure tone audiometry showed bilateral sensorineural deafness.ABR showed no response bilaterally.The 40 Hz AERP showed no response in both ears.OAE showed responses in some or all of the frequencies.No stapedial reflex was detected.The eye movement of Ⅲ-7 and Ⅳ-10 were reasona-ble in all directions,and color vision was normal.Ocular papilla atrophy was observed in different degrees in fundus examination.OCT showed thinning of optic disc nerve fibers in both eyes,and visual evoked potential showed pro-longed P100 wave peak.They were diagnosed as hereditary auditory neuropathy with optic atrophy.A mutation of the OPA1 gene c.1334G＞A(p.Arg445His,NM_015560.2)at a pathogenic locus on chromosome 3 was detected by whole exon detection in Ⅲ-7.The results of generation sequencing analysis showed that the OPA1 gene c.1334G＞A(p.Arg445His,NM_015560.2)mutation of chromosome 3 was also found in Ⅳ-7 and Ⅳ-10.Meanwhile,the gen-otypes of Ⅲ-8 and Ⅳ-9 were wild homozygous,that is,no mutation occurred.Conclusion The OPA1 c.1334G＞A(p.Arg445His,NM_015560.2)mutation site might be the pathogenic mutation in this family.

Objective:To design and develop a molecular imaging probe of 68Ga-labeled bombesin (BBN) analogue, 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)-polyethylene glycol (PEG) 4-BBN, and investigate its potential to target prostate cancer with high expression of gastrin-releasing peptide receptor (GRPR) while minimizing uptake in pancreatic tissue. Methods:Based on the amino acid sequence of BBN peptides, the precursor DOTA-PEG 4-BBN was designed and prepared, followed by labeling with 68Ga and conducting to quality control analysis. The tumor uptake of 68Ga-DOTA-PEG 4-BBN was assessed by microPET/CT imaging on tumor-bearing nude mice models with PC3 of high GRPR expression or HT29 of low GRPR expression (3 mice per group). 68Ga-DOTA-PEG 4-BBN microPET/CT imaging was also performed on 6 tumor-bearing nude mice models with PC3, among which 3 mice were treated with gastrin-releasing peptide antagonist 1 h prior to injection of the tracer (blocked group). After imaging, the ex vivo tissues of 3 PC3 tumor-bearing nude mice of the non-blocked group were examined for radioactivity counting to evaluation the biodistribution of 68Ga-DOTA-PEG 4-BBN, and the percentage injected dose per gram of tissue (%ID/g) was calculated. Independent-sample t test was used for data analysis. Results:The synthesis of 68Ga-DOTA-PEG 4-BBN took 40 min, with the radiochemical yield of 50%-60% (no decay correction) and the radiochemical purity of over 95%. After incubation in the serum at 37 ℃ for 4 h, the radiochemical purity remained more than 95%. The microPET/CT imaging results indicated that the uptake in the PC3 tumor was 3.2 times higher than the uptake in the tumor after GRPR blockade ((1.34±0.24) vs (0.42±0.03) %ID/g; t=5.47, P=0.005). After the injection of 68Ga-DOTA-PEG 4-BBN at 1 h and following imaging for 15 min, the PC3 tumor-bearing nude mice models of the non-blocked group showed that the pancreatic uptake ((0.150±0.058) %ID/g) was significantly lower than that in kidneys, lungs and liver ((9.452±0.234), (0.720±0.041), (1.572±0.213) %ID/g) with a profound statistical distinction ( t values: 11.28-53.02, all P<0.001). The tumor/pancreas uptake ratio could reach 16.92 in the tumor-bearing nude mice models with high GRPR expression. Conclusion:A novel molecular imaging probe 68Ga-DOTA-PEG 4-BBN demonstrates specific recognition of tumors with high GRPR expression while exhibiting low uptake in the pancreas, which shows its potential in prostate cancer molecular imaging.

Objective: Studies on duration of untreated psychosis are common in patients with schizophrenia, but few studies have investigated the relationship between duration of untreated illness (DUI) and suicide, especially in patients with chronic schizophrenia. Therefore, we intended to investigate the relationship between DUI and suicide and clinical correlates in patients with chronic schizophrenia. Methods: A total of 1,555 Chinese patients with chronic schizophrenia were enrolled in this study. DUI was measured in years, reflecting the prolonged untreated periods observed in this population. Clinical correlates were assessed, including symptoms, cognitive functioning, and body mass index. Suicidal ideation and attempts were also examined. Statistical analyses, including multivariate models, were employed to investigate the associations between DUI and clinical correlates while controlling for potential confounders. Results: The study revealed a significant proportion (23.3%) of patients with chronic schizophrenia in China received their first treatment after a 4-year delay, with the longest untreated duration reaching 39 years. Patients with longer DUI exhibited more severe negative symptoms, lower immediate memory scores, a higher likelihood of being overweight, and surprisingly, a reduced likelihood of suicidal ideation and attempts. Each additional year of untreated illness was associated with a 3% decrease in the risk of suicidal ideation and attempts. Conclusion The findings underscore the prevalence of extended untreated periods in Chinese patients with chronic schizophrenia and highlight the impact of DUI on negative symptoms, cognitive function, and body weight. Intriguingly, a longer DUI was associated with a lower risk of suicidal ideation and attempts.

Objective:To identify the risk factors for survival prognosis of patients with early-stage hepatocellular carcinoma (HCC) after ultrasound-guided percutaneous microwave ablation (US-PMMA), and to compare the overall survival (OS), cancer specific survival (CSS) and disease-free survival (DFS) between different early-stage HCC patients.Methods:A total of 1 563 patients with early-stage hepatocellular carcinoma (HCC) who underwent MWA in the interventional ultrasound department of the Chiese PLA General Hospital from January 2002 to December 2017 were retrospectively analyzed. Propensity score matching (PSM) balanced the baseline parameters between the elderly group (≥60 years) and the young group (<60 years). Multivariate Cox regression analysis was used to identify the risk factors of OS, CSS and DFS. OS, CSS and DFS probabilities for different patients stratified by respective predictors were calculated with Kaplan-Meier method and compared using the Log-Rank test.Results:All parameters were balanced except for age after PSM.Tumor diameter(95% CI=1.1-1.4, P<0.001), number of tumors(95% CI=1.2-1.9, P<0.001), γ-GT (95% CI=1.0-1.0, P<0.001) and AFP (HR=1.5, 95% CI=1.2-1.8, P<0.001) were shared predictors for OS, CSS and DFS. Age (95% CI=1.2-1.8, P<0.001) and neutrophile to lymphocyte ratio (NLR) (95% CI=1.0-1.0, P=0.043) were another two predictors for both OS and CSS. Albumin predicted OS only, and sex and cirrhosis just predicted DFS. Over the follow-up period (12-156 months), log-rank tests showed that all predictors significantly affected the corresponding OS, CSS or DFS(all P<0.01). Among them, multiple tumors had the greatest impact on OS, CSS and DFS. Compared with patients with single lesion, OS, CSS and DFS in patients with multiple lesions decreased by 9.2%, 2.5% and 4.1% respectively at the 12 years of follow-up, and the median survival time was shortened by 12.3 months, 25.0 months and 11.3 months, respectively (log-rank P=0.049 for OS; P=0.007 for CSS; P<0.001 for DFS). Conclusions:The prognostic benefits from MWA treating early-stage HCC in patients with different survival risk factors are different. Clinically feasible correction of hypoproteinemia and liver disfunction are of great significance to improve the prognosis of early-stage HCC patients after US-PMMA.

The understanding of heart embryonic development and structure can contribute to improve our leaning of the etiology, pathophysiology and classification of congenital heart disease in humans, which has become the focus of echocardiography teaching. Meanwhile the difficulties and problems formed because of its diverse and fragmented theoretical knowledge. "Hand as foot" teaching method is a kind of teaching method using intuitive body language combined with the thought of analogy, so as to make teaching content relatively simplistic and figurative. Our study has demonstrated this method can be used in a constructive way to improve course content and delivery for echocardiography teaching to assess patent foramen ovale for standardized residency training of cardiac ultrasound, and achieved a good teaching effect. The specific implementation approaches and effect of this method are described in detail. This paper also explores the potential feasibility and benefits of the application of using "Hand as foot" teaching method in echocardiography teaching.

Objective:To explore the clinical effect of the second toenail flap with the dorsal bone of the phalange in repairing the defect of fingernail bed.Methods:From January, 2012 to June, 2019, 10 patients with large area of fingernail bed defect were treated by the second toenail flap with bone on the back of the phalanx. The survival of the flap was observed after the operation, and the fracture healing, the shape of the nail and the flexion and extension function of the finger joint were observed in the outpatient follow-up.Results:All flaps of the second toenail survived. The average follow-up period was 8 (4-12) months. The fractured ends of 10 patients' phalanges healed well without nonunion, good appearance of toenail and deformity of toenail. The recovery of hand function was evaluated according to the evaluation standard of upper limb function of Hand Surgery Society of Chinese Medical Association, 9 cases were excellent, and 1 case was good.Conclusion:The second toenail flap with dorsal bone of the phalanx preserved is easy to cut, simple to operate, and has good clinical effect. It is a good method to repair the defect of the fingernail bed.

Objective:To investigate the relationship between serum ubiquitin C-terminal hydrolase-L1 (UCH-L1) and neuroglobin levels and the prognosis of neurological function in coma patients after cardiopulmonary resuscitation, and to analyze their value in predicting the prognosis of patients.Methods:From February 2018 to June 2020, 45 comatose patients admitted to the Chengdu Third People′s Hospital of Sichuan Province after successful cardiopulmonary resuscitation were prospectively selected as the coma group, and 62 patients admitted to the emergency intensive care unit during the same period after successful cardiopulmonary resuscitation with consciousness recovered within 24 hours were selected as the control group.Serum UCH-L1 and neuroglobin levels were detected within 24 hours after admission.Glasgow coma Scale (GCS)and cerebral performance category(CPC)were used to evaluate coma severity and neurological prognosis.Spearman rank correlation analyzed the correlation between UCH-L1 and neuroglobin levels and GCS and CPC scores.Logistic regression analyzed the factors affecting the prognosis of neurological function in coma patients after cardiopulmonary resuscitation.Receiver operating characteristic curve (ROC) was used to analyze the value of UCH-L1 and neuroglobin in predicting the prognosis of neurological function in coma patients after successful cardiopulmonary resuscitation.Results:In coma group, serum UCH-L1((0.63±0.21) μg/L) and the concentration of neuroglobin ((89.34±21.35) mg/L) was higher than that in the control group ((0.27±0.08) μg/L, (32.13±9.21) mg/L), the difference was statistically significant( t=12.338, 18.846; all P<0.001). The levels of UCH-L1 and neuroglobin in mild, medium and severe coma groups were increased in turn, and the differences between the groups were statistically significant( F=86.430, 26.958; all P<0.001). The serum levels of UCH-L1((0.72±0.06) μg/L)and neuroglobin ((100.35±5.79) mg/L)in the group with poor neurological prognosis were higher than those in the group with good neurological prognosis((0.52±0.08) μg/L, (75.58±6.91) mg/L), and the differences between the groups were statistically significant( t=9.585, 13.086; all P<0.001). UCH-L1 and neuroglobin were negatively correlated with GCS score(rs=-0.685, -0.669; all P<0.001), and positively correlated with CPC score (rs=0.688, 0.670; all P<0.001). Multivariate Logistic regression analysis showed that low GCS score( OR=0.552, 95% CI: 0.392-0.776, P<0.001), high UCH-L1 ( OR=1.881, 95% CI: 1.276-2.773, P<0.001)and neuroglobin( OR=1.677, 95% CI: 1.206-2.331, P=0.001)were independently associated with poor neurological outcomes in coma patients after cardiopulmonary resuscitation .The AUC of combining UCH-L1 and neuroglobin in predicting poor neurological outcomes in coma patients after cardiopulmonary resuscitation was 0.954, which was higher than that of UCH-L1 and neuroglobin alone (0.821, 0.790) ( Z=2.351, 2.649; all P<0.05). Conclusion:After successful cardiopulmonary resuscitation, the levels of UCH-L1 and neuroglobin in coma patients are increased.High levels of UCH-L1 and neuroglobin are associated with coma severity and neurological dysfunction, which can be used as a potential biological indicator for prognosis evaluation of neurological function.
