Background Men who have sex with men (MSM) have become one of the most risky populations for HIV infection in China. Though several cross-sectional sero-prevalence studies have been conducted, the annual HIV incidence remains unknown in this population.
Methods We applied IgG-capture BED-enzyme immunoassay (BED-CEIA) to define the recent HIV-1 infections among MSM in Beijing in the years 2005 and 2006 and the annual HIV incidence was estimated.
Results Overall, 1067 MSM samples were collected, including 526 samples in the year 2005 and 541 in 2006. In 2005, of 17 HIV seropositive samples, 7 were identified as recent HIV-1 infections and the estimated HIV infection incidence was 2.9% per year (95% CI, 0.8%-5.0%). In 2006, of 26 HIV seropositive samples, 9 were identified as recent HIV-1 infections and the estimated annual incidence was 3.6% (95% CI, 1.3%-5.9%), which was 0.7% higher than that in 2005. Individuals engaging in male group sexual intercourse (5.17% vs 0.87%, P=0.019) and having receptive anal sexual intercourse more than five times (2.79% vs 0.33%, P=0.047) in the past 6 months significantly increase the risk of being infected by HIV-1.
Conclusions A high level of annual HIV-1 infection incidence was observed among MSM in Beijing for the consecutive years 2005 and 2006 with a continuous increasing trend. The rising incidence and related high risk behavior among MSM alarmed the health authorities and calls for more effective intervention strategies among this population. 相似文献

To describe the epidemiologic features of an outbreak of severe acute respiratory syndrome (SARS) in urban and suburb areas in Beijing and to explore their differences between these two areas. Methods Data of SARS cases were collected from daily notification of China Ministry of Health and a database of infectious diseases was established by the Beijing Municipal Center for Disease Prevention and Control (BCDC). All the data were put into dataset files by Microsoft Exeel-2000 and analyzed with SPSS version 10.0 software. Results The respective urban incidence and mortality rate were 29.06 and 2.21 per 100 000, while the case fatality rate was 7.62%. In contrast, the respective suburb incidence and mortality rate were 10.61 and 0.78 per 100 000, and the case fatality rate was 7.32%. No significant differences were found in demographic characteristics between the urban and suburb areas. Conclusion Beijing urban area suffered a more serious SARS epidemic than the suburb area in 2003. 相似文献

Preventive mass screening was conducted
every l-2 years in 42 textile factories from 1958-
80 in Shanghai. A total of 846,104 examinations
was made, and the percentage of women ex-
amined was 70-90%. In 23 years the age-
standardized prevalence rate was lowered by
97.6%. 520 cases of cervical cancer were fonnd,
among them 465 patients are still alive. The
10-year survival rate (life-table method) was
93.1%, and the 20-year, 86.1%. There were rio
stage IV, III and II cases in recent 18, 8 and 7
years, respectively. In the past 8 years, all 45
cases except one were of subclinical type. The
average incidence rate of cervical cancer ranked
5th among all malignant cases at these factories,
whereas the mortality rate came down to the
last.
The prevalence rate of cervical cancer in
the ≥40 year old group was over 3 times higher
than in the <40 year old group. During the 23
years the median age of cervical cancer patients
was postponed by 8.7 years. The disease has
not been discovered in <40 year old women in
the last 3 years. Carcinoma in-situ was not
detected in the <40 year old group in the last
8 years. The prevalence rate of cervical atypical
hyperplasia in the ≥40. year old group was 7.5
times higher than in the group. of <48 years.
Therefore women ≥40 years, old are the high risk
group in our series. 相似文献

Objective:To observe the efficacy and safety of total glucosides of paeony capsule(TGPC)in patients with mild and moderate alopecia areata.Methods:A total of 86 outpatients were randomly allocated into two groups of TGPC(treatment,44 cases)and compound glycyrrhizin tablet(control,42 cases).The treatment group was given oral TGPC,three times daily and 600 mg per time;the control group was given oral compound glycyrrhizin tablets,three times daily and 50 mg per time.In addition,both groups were given 10 mg of vitamin B2 and tapped the bold patches with massage.The treatment course was three months for both groups.Peripheral blood T-cell subsets(CD3~+CD4~+,CD3~+CD8~+,Th,Ts,Th/Ts)of 10 patients randomly selected from each group respectively were tested before and after three months of treatment.The effectiveness and adverse reaction of all cases were observed each month.The safety was evaluated according to the incidence rate of adverse reaction. Results:In the treatment group,the cured and markedly effective rate was 36.36%(16/44),50.00%(22/44)and 68.18%(30/44)at the end of first,second and third month of treatment,respectively,and the incidence rate of adverse reaction was 13.64%(6/44).In the control group,the cured and markedly effective rate was 38.10% (16/42),57.14%(24/42)and 71.43%(30/42),respectively,and the incidence rate of adverse reaction was 16.67%(7/42).The cured and markedly effective rate and the incidence rate of adverse reaction were similar in both groups(P>0.05).TGPC and compound glycyrrhizin tablet can inhibit CD3~+CD4~+ and CD3~+CD8~+,and decrease the ratio of Th/Ts(P<0.05).Conclusion:TGPC is effective and safe in the treatment of alopecia areata. 相似文献

Population-based cancer registration data were collected to estimate the cancer incidence and mortality in Wuwei, Hexi Corridor Region, China in 2018. We used the 2011-2013datato predict the number of new cases and deaths in 2018 and the 2003-2013data to analyze trends in cancer incidence and mortality. The goal is to enable cancer prevention and control directions. Our results indicated that stomach cancer is the most common cancer. For all cancers combined, the incidence and mortality rates showed significantly increasing trends (+2.63% per year; P<0.05 and+1.9% per year; P <0.05). This study revealed a significant cancer burden among the population of this area. Cancer screening and prevention should be performed after an epidemiological study of the cause of the cancer is completed. 相似文献

The acute respiratory distress syndrome (ARDS) is defined by noncardiogenic pulmonary edema and acute respiratory failure in the seriously ill patients. It represents the serious pulmonary response to a broad range of severe injuries occurring either directly to the lung or as the consequence of injury or inflammation at other sites in the body. With the great advance in the treatment of serious diseases such as severe trauma, shock and sepsis, many patients do not die of original diseases but develop ARDS, which makes the incidence of ARDS increase. Results from a recent thorough epidemiological study conducted in Seattle suggested ARDS incidence figure of 59 cases per 100000 inhabitants/year.[第一段] 相似文献

An analysis was made of the data from a retrospective epidemiological study of 8766 cases of tubaf tigation performed between 1978 and 1983. Life-tabte statistcal analysis showed a cumutative pregnancy rate of 0.40 / 100 women in the first year, 1.07 / 100 women in the sixth year after tubal ligation. The incidence of complications was 2.66%, among which infection was the first in order. The results of multiple stepwise diseriminant analysis showed that the main factors af[ecting the operations were. the type of operation, and the hospital where the operation was performed. Premeroy rate after Madlener‘s operation was significantly higher than that after Pomeroy, modified Pomerov and Uchida operations. Signfieantlv higher pregnaney rate was observed in cases operated in hospitals below the county level than in those performed above cotatty level. The results of investigation indicated that tubal tigation is a safe, reliable, life-long cotraceptive measure. 相似文献

The overall incidence of psychiatric illness among the physicians of British Columbia during 1970-74 was 1.27% per year. The overall suicide rate was more than 36.5/100 000. Incidence was not dependent on sex or age. The two specialties with the highest incidence--ophthalmology and psychiatry--had previously been demonstrated to have significantly high rates of suicide. The highest incidence was among psychiatric residents; in other resident groups collectively the incidence was at the expected rate. Greater severity of illness and poorer prognosis was found in family physicians compared with specialists, although the incidence was the same in the two groups. 相似文献

Attempted suicide in Adelaide and Perth: changing rates for males and females, 1971-1987 总被引:1,自引:0,他引:1
OBJECTIVE: Official rates of attempted suicide in Perth, in 1971-1972 and 1986-1987, were examined, with the aim of documenting changes in the age and sex distribution of persons who attempted suicide over the 15-year period. In addition a survey of all patients presenting to the Royal Adelaide Hospital between 1986 and 1988 aimed to determine whether or not the official figures accurately reflect the number of presentations for attempted suicide. DESIGN AND SETTING: Rates of attempted suicide were calculated from the Hospital Morbidity Data for hospitals in the Perth Statistical Division and from the Inpatient Separations Information System (ISIS) for hospitals in the Adelaide Statistical Division. Rates were expressed for each sex as annual age-specific rates per 100,000 population. The data were age-standardised by the direct method. A survey was completed of all patients presenting to the Royal Adelaide Hospital between 1986 and 1988 after attempted suicide. The findings were compared with the official figures for the Royal Adelaide Hospital and were used to estimate the actual rate of attempted suicide in the Adelaide Statistical Division. RESULTS: In Perth the rate of attempted suicide for males increased from 93 per 100,000 in 1971-1972 to 137 per 100,000 in 1986-1987. The increase was most striking in the age groups 15-19 and 40-44 years. The rates for females decreased from 214 per 100,000 to 195 per 100,000. In Adelaide, from 1986 to 1987, between one-fifth and one-third of persons who attempted suicide and presented to the Royal Adelaide Hospital were not recorded in the ISIS. In 1988, two-thirds were not recorded. We estimated that the real rate of attempted suicide for males in Adelaide was about 180 per 100,000 and for females was about 250 per 100,000. CONCLUSIONS: Our understanding of the epidemiology of attempted suicide is largely based on data which are now out of date. The Perth findings of a 47% rise in rate among males and a 9% fall among females suggest that attempted suicide is no longer a behaviour more associated with females than males. The Adelaide survey data demonstrate that official rates for attempted suicide underestimate the extent of the phenomenon in the community by a significant margin. An attempted suicide register is suggested as a method of overcoming this problem. 相似文献

We reviewed the epidemiologic features of suicide in Canada and evaluated suicide prevention programs. Three groups were found to be at increased risk for suicide: men aged 70 years or more, women aged 65 to 69 and men aged 20 to 24. The other groups, in decreasing order of risk, were the mentally ill, people who have attempted suicide, those with a life-threatening illness, native people, people with a family history of suicide and prisoners. Studies that evaluated suicide prevention programs showed that none significantly reduced the incidence of suicide; however, the studies were found to be methodologically inadequate or used noncomparable systems of data collection. On the basis of our findings we recommend that primary care physicians routinely evaluate suicide risk among patients in high-risk groups and that intervention include counselling, follow-up and, if necessary, referral to a psychiatrist. Close follow-up is recommended for newly discharged psychiatric patients and those who recently attempted suicide. 相似文献

The suicide rate in Singapore has remained at 9-11 per 100,000 over the past decade. Comparing the age specific suicide rate, elderly people (60 years and above) have a much higher rate (21.3 per 1000,000) than the young (5 per 100,000). The data also indicate that elderly men are more prone to kill themselves than elderly women. Risk factors in elderly suicide and preventive measures are discussed. 相似文献
