A survey and analysis were conducted at the end of 2002 of urban community health service institutions in 31 provinces, autonomous regions and municipalities directly under the Central Government so as to find out about the basie situation of community health service institutions across the country. The result indicated that by the end of 2002, the number of cities that had conducted community health service work reached 358. The coverage of community health services in cities of the prefecture level, areas under the jurisdiction of a city and cities of the county level was respectively 92. 1%, 80. 3% and 28.0% . 12 132 community health service institutions were set up in 2002, marking an increase of 31.6% as compared with 2001. The growth of community health services was fast and yet uneven in various regions. It is suggested that more efforts be made to strengthen community health services in medium-sized and small cities and improve the management of institutions and the system for statistical analysis of in-formation.

Objective Cloning of some specific genes related to the prostate cancer. Methods Specimen from a patient with prostate cancer and from a normal adult were studied by the improved mRNA differential display and the differentially expressed sequence-tags were cloned,sequenced and analized.Reverse transcriptive-polymerase chain reaction(RT-PCR) was used to examine the expression level of Clusterin in prostate cancer tissues,prostate cancer cell line and normal prostate tissues. Results Significant difference was observed between the two kinds of tissues in gene expression and seven differentially expressed sequence-tags were found through analysis in GenBank.Among them,five were proved to be new gene tags,one shared 100% homology with Clusterin,which was highly expressed in the prostate cancer tissue and the other one shared 97% homology with superoxide dismutase 1 (SOD1),which was highly expressed in the normal prostate tissue.It was proved by RT-PCR that to compare with the internal marker gene ?-actin,the expression level of clusterin in prostate cancer is much higher than that of normal prostate. Conclusions Five new gene tags,clusterin and SOD1 were found to be differentially expressed between tissues of prostate cancer and normal prostate and may play important roles in carcinogenesis and development of prostate cancer.

Objective To assess the value of laparoscopy in the diagnosis and treatment of abdominal emergency during pregnancy.Methods Clinical data of 40 cases of abdominal emergency at 7~17 gestational weeks(mean,13.2 weeks) from June 1997 to October 2004 were retrospectively reviewed.There were 16 cases of uterine with ectopic pregnancy,3 cases of twisted ovary,5 cases of pedicel torsion of ovarian cyst,5 cases of acute cholecystitis,and 11 cases of acute appendicitis.The diagnosis and treatment were conducted under laparoscope. Results The confirmative diagnosis was clarified under laparoscope in all the cases.Except 1 case of conversion to open surgery,the operation was accomplished laparoscopically in all cases. The operation time was 25~70 min(mean,38.2 min).Surgical complications occurred in 1 case.During postoperative follow-up observations,there were 3 cases of threatened abortion,3 cases of inevitable abortion,and 1 case of premature delivery. Conclusions Laparoscopic operation is safe and effective for acute abdominal emergency during early-to-middle pregnancy.

Objective:To investigate changes of the stage,age of onset,and prostate specific antigen(PSA) level of prostate cancer with socioeconomic development and medicare promotion.Methods:The medical records of 784 inpatients with prostate cancer were analyzed retrospectively,who were diagnosed in Peking University First Hospital from 1997 to 2007.According to the time of diagnosis,all the patients were sorted into three groups:earlier group(1997-2001),intermediate group(2002-2004),and contemporary group(2005-2007).The tumor stages,ages,Gleason scores,and PSA levels of each group and of the three groups were compared to determine whether the discrepancies were significant.Results:The discrepancies of ages,Gleason scores,and stages between earlier and intermediate groups were not significant.The differences of ages and stages between intermediate and contemporary groups were not significant,but the change of Gleason scores was significant.The discrepancies of Gleason scores and stages between earlier and contemporary groups were meaningful,but the change of ages was not significant.Conclusion:As time passes,PSA levels and tumor stages of prostate cancer patients show a descending trend,but the discrepancy of ages between the three groups is meaningless.The weight of low risk and intermediate risk groups in localized prostate cancer is becoming heavy.

Objective To study the killing effect of hypocrellins B-photodynamic therapy (HB-PDT) for lung cancer cell line A549, to compare with that of hematoporphyrin derivative-photodynamic therapy (HpD -PDT), in order to define the superiority of HB-PDT in the therapy of lung cancer. Methods Lung cancer cell line A549 was used in the study. The cells were incubated in vitro with HB or HpD dissolved in DMEM in different concentrations, and then irradiated by copper vapor laser with mixed wavelength light under saturated light dose. Cell survival rate was respectively measured by MTT assay after 24 hours' incubation. According to cell survival curves after being cultured with different photosensitizers in different concentrations, the equation of each cell survival curve was plotted. Finally IC 50 (50% inhibition concentration) of each photosensitizer was derived. Results The results showed that HB-PDT had a strong killing effect on lung cancer cell. The IC 50 of HB was 33.82ng/ml for lung cancer cell, while the IC 50 of HpD was 1 316.88ng/ml, which was 38.94 fold of that of HB. Conclusions HB was a more effective photosensitizer than the photosensitizer HpD. HB-PDT had strong photodynamic killing effect on lung cancer cell line.
