Effects of XRCC1 Polymorphism on Efficacy of Chemotherapy and Survival Time of Advanced Gastric Cancer Patients / 中国药房

OBJECTIVE:To investigate the effect of X-ray repair cross complementing gene(XRCC1)Arg399Gln(G→A) polymorphism on efficacy of oxaliplatin+fluorouracil chemotherapy and survival time of advanced gastric cancer patients. METH-ODS:Totally 52 cases of advanced gastric cancer were selected from Hainan Provincial People's Hospital during Jan. 2013-Jan. 2015. They were given oxaliplatin+fluorouracil chemotherapy,for 3 courses(a treatment course lasted for 3 weeks). The genotypes of patients were detected by PCR-LDR. Disease control rate and progression free survival were compared among different geno-types. RESULTS:Among 52 cases of advanced gastric cancer,there were 28 cases of XRCC1 GG genotype(53.8%),21 cases of GA genotype(40.4%),3 cases of AA genotype(5.8%),frequencies of which were all in line with Hardy-Weinberg balance(P>0.05). Disease control rates of 52 cases were 76.9%,among which disease control rate(92.9%)of GG genotype was significantly higher than that of GA+AA genotype(58.3%),with statistical significance(P<0.05). The average progression free survival of 52 cases was(7.1+1.2)months,among which progression free survival of GG genotype [(8.6±0.8)months] was significantly longer than that of GG+GA genotype [(5.9 ± 0.7)months],with statistical significance (P<0.05). CONCLUSIONS:XRCC1 polymor-phism is correlated with efficacy of oxaliplatin+fluorouracil chemotherapy and progression free survival,and XRCC1 GG genotype is more sensitive to chemotherapy drugs. XRCC1 gene can be regarded as predictive indicator for therapeutic efficacy of chemothera-py and survival.

Analysis of periodontal health status and its related factors in the elderly in Haikou city / 中华老年医学杂志

Objectives To investigate the prevalence rate of periodontal diseases in the elderly aged 65～74 years in Haikou,and to provide basic data for the diseases prevention.Methods A total of 875 residents(aged 65-74 years)were selected using stratified random sampling in four areas of Haikou,and oral health checks were conducted.Results The prevalence rate of periodontal disorders,such as gingival bleeding,dental calculus,periodontal pockets was 57.8％,83.5％ and 24.0 ％,respectively.In average,9.2 (gingival bleeding),16.6 (dental calculus) and 1.7 (periodontal pockets)teeth were detected in each person.Detection rate of loss of periodontal attachment(LOA)of ≥4 mm(at least 1 teeth)was 55.7％,while the percentages of LOA ≥ 6 mm(at least 1 teeth)declined to 17.6％.Binary Logistic regression analysis showed that dentures were a risk factor for bleeding gums.With aging,risk of the formation of dental calculus became lower.The risk of the formation of dental calculus was 1.98 times higher for the elderly without denture than for the elderly with denture.The risk of the formation of periodontal pockets was higher in men than in women.The risk of the formation of periodontal pockets became higher in the elderly from poor families.The risk of the LOA≥ 4 mm was 1.40 times higher for rural original-addressed elderly than for urban originaladdressed elderly,and smoking and drinking were risk factors for LOA≥4 mm.Conclusions The periodontal health status of the elderly in Haikou is not optimistic.Factors affecting periodontal health are multifaceted.Therefore,appropriate measures should be taken to improve the oral health status of older persons.

Care burden and its influencing factors of primary caregiver of patients with spinal cord injury / 中国实用护理杂志

Objective To explore the care burden and its influencing factors of primary caregiver of patients with spinal cord injury. Methods A total of 120 primary caregiver of spinal cord injury patients were selected as research object. The general information of SCI patients and their primary caregiver were investigated by SCI patient general data questionnaire and primary caregiver in SCI patient general data questionnaire, caregiver burden of spinal cord injury were investigated bycaregiver burden inventory. The relationship between the general information of patients and caregivers and the care burden analyzed. Results Caregiver burden of elderly patients was significantly lower than that of younger ones (F=54.053,P<0.01). The more serious of spinal cord injury, the higher of care burden (F=315.104,P<0.01). The patients with neck and multiple segmental spine injury and postoperative complications had a higher care burden (F=199.203,t=6.462, 32.195,P<0.01). When the caregivers were female, spouses or children, with poor health condition, with higher education degree, and as cadres or workers, caregiver burden was higher (t=6.061,F=22.073-52.392,P<0.01). Multiple linear regression analysis showed that the degree of spinal cord injury, complications, gender, and the relationship between the patients were the main factors that influenced the care burden. Conclusions The main factors influencing the care burden are spinal cord injury degree, complications, gender, and the relationship between the patients. Clinical managers needs to develop appropriate social support system for the factors which affect the caregiver, in order to ease the caregiver′s care burden.

To assess the prognosis of patients with return of spontaneous circulation after cardiac arrest by shock index and adjusted shock index / 中华急诊医学杂志

Objective To examine the usefulness of shock index (Sl) and adjusted shock index (corrected to temperature) (ASI) in predicting prognosis of patients with return of spontaneous circulation after cardiac arrest.Methods A prospective study,which data such as vital signs of the cases were collected by the Utstein template,was conducted in 111 of cases with return of spontaneous circulation after cardiac arrest to assess the value of SI and ASI for predicting their prognoses.Results There was no evidence to show difference between the cases with survival to hospital discharge and the ones who died about systolic blood pressure and heart rate (P ＞0.05).SI and ASI [(1.109 ±0.428) and (1.082 ±0.410)] of the group of death were higher significantly than the ones [(0.899 ± 0.303) and (0.844 ± 0.265)] of the group with survival to hospital discharge,P ＜ 0.05.The risk of death was elevated in the group with ASI ＞ 1.1,which odds ratio (5.4) higher than the ones of systolic blood prcssure ＜90 mm Hg (1.6)and ventricular rat ＞ 100 beat/min (3.1) significantly.The odds ratio of death with AS ＞ 1 was 2.8.Conclusions Shock index and adjusted shock index are easy to derive and conducive to predict effectively diseases prognosis such as survival to hospital discharge or death of patients with ROSC.

A prospective investigation of the epidemiology of in-hospital cardiopulmonary resuscitation using the international Utstein reporting style / 中华急诊医学杂志

Objective To investigate the usefulness of Utstein template to guide the assessment and study of cardiopulmonary resuscitation (CPR) in our medical practice because it has been popularized in many countries since 1991.Methods A prospective observational study using Utstein CPR registry form to evaluate the epidemiological features and outcomes of 511 patients resuscitated in the emergency department.Results Of 511 CPR patients registered,higher cardiac arrest rates were observed in the group of patients aged 40- 70 years. In 511 CPR patients registered,preexisting chronic diseases were common including cardiovascular diseases ( 190,37.2％ ) cerebrovascular diseases (48,9.4％ ) and respiratory diseases (39,7.6％ ).Of them,173 cardiac arrest patients (33.9％) had underlying cardiac causes,such as acute myocardial infarction (AMI) found in 109 (21.3％) patients,and ventricular fibrillation witnessed during first cardiac monitoring in eighty ( 15.7％ ) patients.The restoration of spontaneous circulation (ROSC) rate and survival rate at discharge of in - hospital cardiac arrest (IHCA) patients were 47.0％ and 13.5％respectively,but 16.7％ and 4.7％ respectively in the out - hospital cardiac arrest (OHCA) patients (P ＜0.01,both ). Conclusions This study indicated that the cardiovascular diseases, cerebrovascular diseases,and respiratory diseases were the most common preexisting chronic diseases found in cardiac arrest patients.Myocardial infarct,stroke and trauma were the most common precipitation causes of cardiac arrest in the recruited patients.The rates of ROSC and survival at discharge were significantly higher in statistics in patients with IHCA than those in ones with OHCA.

A multi- centre study of cardiopulmonary resuscitation by using the Hainan Utstein templates for resuscitation registries / 中华急诊医学杂志

Objective To study the Hainan Utstein templates used for cardiac arrest and resuscitation registries to evaluate the epidemiological characteristics and outcomes of the patients with CPR by multi-center study. Methodsccording to the Utstein templates for cardiac arrest and CPR set by International Liaison Committee on resuscitation in 2004, a Hainan Utstein CPR registry chart was designed and a prospective descriptive study was carried out to evaluate the epidemiological characteristics, impact factors and outcomes of the patients with resuscitation attempt in emergency departments of thirteen hospitals in Hainan Island between January 2007 and December 2010.Results Of 1125 patients with cardiac arrest, male accounted for 73. 8％ and female was 26. 2％. The mean ( ± S. D) age of the cardiac arrest patients was 53.9 ± 13. 1 years old.Coronary heart diseases and hypertension were the most common preexisting chronic diseases in the studied patients. The ROSC rate and discharge rates after survival in 1125 patients with CPR were 23. 8％ and 7.4％ respectively. The ROSC rate and discharge rates after survival were 36. 3％ and 11.6％ in the in-hospital cardiac arrest (IHCA) group, respectively whereas 11.5％ and 3. 3％ in out-hospital cardiac arrest (OHCA) group. Of 188 patients with ventricular fibrillation/Pulseless ventricular tachycardia, the ROSC rate and discharge rate after survival were 58.0％and 21.8％,respectively. Of them, 448 (39. 8％ ) of the cardiac arrest patients had underlying cardiac causes, and the ROSC rate and discharge rate after survival were 36. 3％ and 11.5％ respectively in IHCA group whereas 11.6％ and 3. 3％ in OHCA group. The ROSC rate and discharge rate after survival were 69. 8％ and 7. 4％respectively in the tertiary hospitals whereas 30. 2％ and 7. 3％ in the secondary hospitals. Conclusions Patients experienced cardiac arrest were predominantly male. Coronary heart disease and hypertension were the two most common preexisting chronic diseases. The ROSC rate and discharge rate of patients with IHCA were higher than those with OHCA. ROSC rate and discharge rate after survival were higher in the ventriculat fibrillation/Pulseless ventricular tachycardia group than the other cardiac rhythms first witnessed groups. The time delayed of starting CPR after onset of cardiac arrest had a critical impact on survival and discharge rate in both IHCA and OHCA groups.
