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.

Objective To understand the mental health status of residents aged 15 years old or above in Hainan Province,and and to analyze its influencing factors to provide a scientific basis for improving the psychological health level of populations.Methods A multistage randomsampling method was used to extract 3 295 residents in Hainan Province and perform the investigate on the mental health status.Results Among 3 295 surveyed residents,410 respondents had mental disease,accounting for 12.44％ of respondents total number.The total score of SCL-90 in the residents of Hainan Province was lower than that of the national norm(t=14.65,P=0.00).(2)The morbidity of mental disease had no statistical difference between different genders(wald x2 =0.27,P=0.60);which had statistical difference among marital status,environmental satisfaction and family harmony (wald x2 =46.53,P =0.00;wald x2 =51.98,P =0.00;wald x2 =89.47,P =0.00).(3) The non-conditional Logistic regression analysis results showed that the influencing factors entering the regression equation were marital status(OR=0.52),family type(OR =0.57;0.53),environment satisfaction(OR=1.26),family harmony(OR=1.31),health self-examination(OR=0.72),borrowing 5 000 yuan within 2 d when urgent need(OR=1.31) and general well-being(OR=0.86).Conclusion The factors influencing mental illness in residents are multiple,so synthetic measures should be taken for its prevention.

Objective To detect T-lymphocyte subgroup in patients with malignant lymphoma, and investigate the relationship between the number of the cells and the oncogenesis and development of malignant lymphoma. Methods The counts of T-lymphocyte subgroup in peripheral blood of 106 patients with lymphoma were detected by flow-cytometry, and analyzed in comparison with that of 106 normal people as control. Results The counts of CD+3 cell and the ratio of CD+4/CD+8 in patients with malignant lymphoma were significantly lower than that of control group (P＜0.05). The number of CD+3 were significantly lower and CD+8 were higher than that of control group in patients with NHL at early ( Ⅰ, Ⅱ ) stage (P＜0.05). The counts of CD+3 CD+4 cell and the rate of CD+4/CD+8 in patients with NHL at advanced (Ⅲ ,Ⅳ) stage were significantly ldwer than that of control group (P＜0.05). Conclusion The function of immune is decreased in patients with malignant lymphoma, and these changes had correlation with clinic stage. It is of active significance by detecting T-lymphocyte subgroup in peripheral blood in patients with malignant lymphoma to evaluate the function of immune and find out the relationship between the number of the immune cells and the oneogenesis and development of malignant lymphoma.

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.

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.

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.

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.

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.

BACKGROUNDPost-traumatic stress disorder (PTSD) is a mental disorder with delayed or chronic onset caused by unusual, threatening, or disastrous psychological trauma, and it is an important manifestation of post-disaster mental and behavioral disorders. Studies have shown that IL-6 is a cytokine associated with PTSD occurrence. This study aimed to explore the role of cytokine and ethnicity in the pathogenesis of PTSD by examining levels of serum cytokines IL-2, IL-6, IL-8, TNF-α, and cortisol in PTSD patients of Li and Han ethnic groups.

METHODSLevels of serum cytokines IL-2, IL-6, IL-8, TNF-α, and cortisol were examined by enzyme-linked immunoabsorbent assay (ELISA) method and assessed by PCL-C scale among 30 PTSD patients of Han ethnicity and 30 of Li ethnicity, and compared with 30 normal controls of Han and Li ethnicity, respectively.

RESULTSPTSD patients of Li ethnicity scored higher than PTSD patients of Han ethnicity, and normal controls of Li and Han ethnic groups in each of the re-experiencing, avoidance/numbing, and hyperarousal symptoms. The differences reached statistical significance (P < 0.05). In PTSD patients of Li ethnicity compared to patients of Han ethnicity and normal controls of either Li or Han ethnicity, the levels of IL-2, IL-6, IL-8, and TNF-α were higher, and the level of cortisol was lower.

CONCLUSIONSThere are ethnic differences in re-experiencing, avoidance/numbing, and hyperarousal symptoms among PTSD patients. The levels of serum cortisol and cytokines are strongly associated with the race.
