Objective:To count and analyze the residue of narcotics for injection after the use in operation rooms in order to find the possibility of risk avoiding and management standardization. Methods:A retrospective research method was adopted to count and analyze 10268 prescriptions including narcotics for injection in operation rooms from June to August in 2014. Results:Ketamine hydro-chloride injection had the largest residue and its remaining amount also occupied the largest proportion of medication. The second one was pethidine hydrochloride injection and the third one was remifentanil hydrochloride for injection. The highest ratio of remaining a-mount in each prescription was ketamine hydrochloride injection, and the second one was morphine hydrochloride injection and pethi-dine hydrochloride injection ranked the third. Conclusion:It is suggested to reduce the specification of medication with the highest ra-tio of remaining amount in each prescription such as ketamine hydrochloride injection, and improve the management efficiency for the use of narcotics in operation rooms.

Objective: To investigate the influence of different variable combinations of the carrying system on gait and muscle fatigue during weight-bearing walking on both shoulders and back, and to optimize daily carrying experience. Methods: From September to December, 2018, 6 male college students were selected as subjects; the electromyographic signal of the anterior tibial muscle and plantar pressure were measured during weight-bearing walking under six different variable combinations of the carrying system (with the three variables of gravity center, single or double shoulders, and waist cushion), and a subjective evaluation test was performed for the degree of fatigue. The electromyographic data and plantar pressure data were processed and compared to evaluate behavior and fatigue. Results: Different variable combinations of the carrying system had significant influence on the degree of fatigue and gait (P<0.05). Both subjective and objective analyses found that the carrying system with different heights of gravity center and single-or double-shoulder carrying mode had great influence on human fatigue and walking gait, while the hardness of waist cushion had little influence. Compared with the other groups, the group with a high gravity center, a double-shoulder carrying mode, and a soft waist cushion had a significantly smaller slope of average electromyographic amplitude, a significantly larger slope of median frequency, and a significantly lower degree of plantar pressure curve disorder. Conclusion The carrying system with a relatively high gravity center, a double-shoulder carrying mode, and a soft waist cushion can significantly relieve fatigue, with low influence on walking gait.

Objective To study the treatment of highly active antiretroviral therapy (HAART) in patients with HIV infection and AIDS and the patients′ survival time after HAART treatment. Methods Three thousand and one hundred cases of HIV infection and AIDS patients received HAART in 12 months by monthly flow cytometry instrument MultiSET absolute counting method detecting the CD4+T cell levels, bDNA method (detection range 1.60 log ~ 6.10 log RNA copies/mL) detecting serum HIV-1 viral load under rigorous clinical observation. Results Twelve months after treatment, the CD4+T cell count increased an average of 430 × 106/L (P < 0.01). Eight months after treatment, all viral loads reached their measurable levels (below 1.70 log copies/mL) by decreasing 45 log copies/mL on average. Conclusion HIV/AIDS patients showed treatment extremely significant possitive responses to highly active antiretroviral therapy. The patients′ survival rate after treatment has greatly improved compare to that in previous literature.

Objective To investigate the relationship between molecular subtypes of breast cancer and postoperative loco-regional recurrence (LR) in early breast cancer patients with 1-3 positive axillary lymph nodes (pN1) and to improve the individualized indications for post-mastectomy radiotherapy (PMRT)in these patients.Methods A total of 547 patients with pT1-2 N1M0 breast cancer,who received mastectomy between December 1998 and December 2009 in Sun Yat-sen University Cancer Center,were retrospectively analyzed.None of them received adjuvant radiotherapy after mastectomy.The patients were divided into luminal A group,luminal B group,HER-2-overexpressing group,and triple-negative group according to the molecular subtypes of breast cancer determined by immunohistochemistry and fluorescence in situ hybridization.The patients in different groups were compared in terms of LR rate (LRR) and LR-free survival (LRFS),and the risk factors for LR were analyzed in combination with clinical and pathological features.The Kaplan-Meier method was adopted to calculate LRR and LRFS;the Logrank test was used for survival difference analysis and univariate prognostic analysis.The Cox proportional hazards model was used for multivariate prognostic analysis.Results The luminal A group,luminal B group,HER-2-overexpressing group,and triple-negative group accounted for 30.0％,48.6％,9.3％,and 12.1％,respectively,of all the patients.The follow-up rate was 97.1％ ;334 patients were followed up for at least 5 years,and 127 were followed up for at least 10 years.Univariate analysis showed that,compared with the luminal A group,the HER-2-overexpressing group and triple-negative group had significantly higher 5-year LRRs (19.0％ vs 5.3％,x2 =4.28,P =0.026; 14.9％ vs 5.3％,x2 =5.02,P =0.015) and significantly lower LRFSs (73.5％ vs 91.1％,x2=7.27,P=0.005;80.6％ vs 91.1％,x2=4.77,P=0.021).Multivariate analysis revealed that HER-2 overexpression,triple-negative phenotype,age of ≤ 35 years,and stage pT2 were poor prognostic factors for survival (LRR and LRFS) (x2 =2.29,2.08,18.22,and 6.86,P =0.020,0.016,0.001,and 0.005;x2 =1.90,1.41,8.58,and 3.94,P=0.006,0.025,0.002,and 0.039).The 10-year LRRs of patients with 0,1,and ≥2 of the above risk factors were 4.3％,14.1％,and 31.9％,respectively (x2 =28.03,P =0.000).Conclusions Molecular subtyping is helpful for individualized evaluation of LR risk in early breast cancer patients with 1-3 positive axillary lymph nodes (pN1).PMRT should be recommended for the patients with 2 or more risk factors for LR.

Objective:To statistically analyze the prescription writing norms of narcotic drugs for injection in the operation room and inpatient area of our hospital to improve the prescription writing quality and the efficiency of management. Methods:A retrospec-tive research method was adopted, and 17 103 prescriptions for narcotic drugs for injection in the operation room and inpatient area were collected and analyzed from June to August in 2014. Results:The irregular proportion of prescriptions of narcotic drugs for injec-tion was 9. 05%, and the abnormal item was lack of the text. The proportion of prescriptions using residual amount and needing to be marked was 4. 01%. Conclusion: Improving the management and unifying the prescriptions of narcotics, or applying the electronic prescription if allowed will improve the quality of prescriptions of narcotics and achieve the purpose of fine management.

Objective:To investigate the residual narcotics for injection after used in wards in order to provide evidence for the use standardization of narcotics for injection. Methods:A retrospective research method was adopted. Totally 5 288 prescriptions including narcotic drugs for injection in wards were collected and analyzed from June to August in 2014. Results:Only four kinds of narcotics for injection were used in wards, the residual proportion of morphine hydrochloride injection and pethidine hydrochloride injection was 2%, and that of fentanyl citrate injection was 0. 2%. Conclusion:The residue of narcotics for injection in wards is very little, and the specifi-cations of the medication in our hospital meet the demands of clinics. The research is beneficial to improving the management efficiency.

Objective The abnormal ankle-brachial index ( ABI) is associated with the incidence of cardiocerebral vascular diseases, but little is known about its relationship with cerebral microbleeds (CMB).This study aimed to investigate the correlation be-tween ABI≤0.9 and different distribution patterns of CMB . Methods We enrolled 187 patients with acute lacunar infarction , inclu-ding 115 non-CMB cases and 72 CMB cases (20 strictly lobar, 24 strictly deep, and 28 lobar and deep).We analyzed the differences between the two groups and the association of abnormal ABI with the occurrence and distribution of CMB by logistic regression analysis . Results ABI≤0.9 was found in 57 (30.5%) of the patients, with a significantly higher incidence rate in the CMB group than in the non-CMB group (43.1%vs 22.6%, P=0.003).The level of ABI was negatively correlated with the number of CMBs (r=-0.211, P=0.006).Multivariate logistic regression analysis after adjusted for confounders indicated that ABI ≤0.9 was significantly associated with the presence of CMB (OR=2.363;95%CI:1.181-4.729), deep CMB (OR=3.434;95%CI:1.283-9.187), and lobar and deep CMB ( OR=2.837;95%CI:1.098-7.333) in patients with ischemic cerebrovascular disease . Conclusion Decreased ABI is a risk factor of CMB, particularly deep CMB, in patients with ischemic stroke.

Objective To investigate the risk factors for reduced renal function in patients with ischemic stroke.Methods The medical records of patients with ischemic stroke were analyzed retrospectively.They were divided into normal renal function group and reduced renalfunction group.Reduced renal function was defined as estimated glomerular filtration rate (eGFR) ＜60 ml/(min·1.73 m2).Multivariate logistic regression analysis was used to identify the risk factors for reduced renal function in patients with ischemic stroke.Results A total of 805 patients with ischemic stroke were enrolled in the study.8.8％ of patients had a reduced renal function.There was no significant differences in the proportion of patients with mild and moderate neurological deficit between the reduced renal function group and the normal renal function group (all P ＞ 0.05),however,the proportion of patients with severe neurological deficit was significantly higher than that in the normal renal function group (8.4％vs.2.6％,x2 =5.573,P =0.017).The proportion of small artery occlusion in the reduced renal function group was sigaificantly higher than that in the normal renal function group (66.2％ vs.46.5％,x2 =9.962,P =0.002),and the proportion of large artery atherosclerosis was significantly lower than that in the normal renal function group (19.7％ vs.43.5％,x2 =15.045,P =0.000).Multivariate logistic regression analysis indicated that old age (odds ratio [ OR] 3.301,95％ confidence interval [ CI],1.575 to 6.918; P=0.002) was the most important independent risk factor for reduced renal function,then was female (OR,2.291,95％ CI 1.355to 3.872; P=0.002) and hyperlipidemia (OR,2.527,95％ CI 1.095 to 5.831; P=0.030).Conclusions Reduced renal function in patients with ischemic stroke is strongly associated with old age,female,and hyperlipidemia.
