Objective To observe the dynamic changes of CPP32 mRNA in hippocampus following temporary whole cerebral ischemia in rats and to explore the mechanism of neuron apoptosis induced by cerebral ischemia.Methods The model of temporary whole cerebral ischemia in rats were induced by carotid artery negative pressure shunt and the expression of CPP32 mRNA were detected with fluorescence quantify RT PCR.Results Compared with the naive group, the expression of CPP32 mRNA did not increase insignificantly in sham operation group. Compared with sham operation group, the expression of CPP32 mRNA in ischemia group trended to increase at 6 h after ischemia and increased by 53% at 12 h and 223% at 24 h after ischemia. It kept in high level and decreased at 72 h after ischemia.Conclusion The expression of CPP32 mRNA in hippocampus could be induced by temporary whole cerebral ischemia. It began to increase at 6 h, reached its fastigium at 24 h and tended to decrease at 72 h after ischemia. The enhanced gene transcription of CPP32 plays an important role in the neuron apoptosis induced by cerebral ischemia.

OBJECTIVE:To evaluate the efficacy and safety of salmon calcitonin plus Xianling gubao for osteoporosis and ostealgia in postmenopausal women. METHODS:160 women with postmenopausal osteoporosis and ostealgia were randomized to 3 groups (treatment group and 2 control groups):the treatment group received(500 IU q.d) salmon calcitonin nasal spray plus Xianling gubao(1.5 g b.i.d orally); the control group Ⅰ received(500 IU q.d) salmon calcitonin nasal spray alone and the control group Ⅱ received Xianling gubao(1.5 g b.i.d orally) alone. All the patients received oral Caltrate D (1 tablet q.d). A course was defined as 30 days. After treatment for a total of 3 courses,the nature and degree of ostealgia in all the patients were assessed,and the outcome indexes were measured and the adverse drug reactions were recorded. RESULTS:There were significant differences between the treatment group and two control groups in total effective rates(92.59% for treatment group vs. 69.81% for control group Ⅰ and 67.92% for control group Ⅱ,P0.05). CONCLUSION:Treatment of osteoporosis and ostealgia in postmenopausal women with salmon calcitonin plus Xianling gubao has been proved to be safe and effective in that the bone density can be increased effectively and the osteoporotic pain of lumbar and back of the patients can be relieved.

Multiple myeloma is a neoplasm of mature and immature plasma cells, it remains an incurable disease using conventional chemotherapy and increasing aggressive approaches. In recent years, due to the better understanding of myeloma biology, genetics and tumor formation, there are lots of new active drugs or combinational chemotherapy regimens having been developed, such as proteasome inhibitors, immunomodulatory agents etc, they are more effective than conventional chemotherapy. This article summarizes the recent advances with the new options for the treatment of multiple myeloma.

Objective: To investigate the trends in mortality and life lost due to female breast cancer among in Suzhou City from 2007 to 2021, so as to provide insights into improvements of breast cancer control strategy in Suzhou City. Methods: The epidemiological and clinical data pertaining to dead female breast cancer cases in Suzhou City from 2007 to 2021 were collected from Suzhou Municipal Chronic Disease Surveillance System, including gender, age and cause of death. The crude mortality, standardized mortality, years of potential life lost (YPLL), years of potential life lost rate (YPLLR), standardized YPLL (SYPLL), standardized YPLLR (SYPLLR) and average years of life lost (AYLL) due to female breast cancer were calculated. All data were standardized by the Fifth National Population Census in 2000, and the trends in mortality of breast cancer were estimated using average annual percent change (AAPC). Results: Totally 4 425 death occurred due to female breast cancer in Suzhou City from 2007 to 2021, with a crude mortality rate of 8.67/105, which appeared a tendency towards a rise (AAPC=1.83%, t=5.080, P=0.001), and the standardized mortality was 4.68/105, which appeared no significant changes (AAPC=0.13%, t=0.356, P=0.727). The crude mortality rates of female breast cancer were 0.62/105, 10.33/105 and 21.69/105 among women at ages of 15 to 34, 35 to 64 years and 65 years and older, respectively, which appeared a tendency towards a rise (χ2trend=2 315.683, P=0.001). The crude mortality of female breast cancer was 8.66/105 in urban areas and 8.86/105 in rural areas, both appearing a tendency towards a rise (urban areas: AAPC=1.73%, t=3.290, P=0.006; rural areas: AAPC=2.68%, t=6.565, P=0.001). The YPLL, SYPLL, YPLLR, SYPLLR and AYLL of female breast cancer were 44 485 person-years, 30 387 person-years, 0.99‰, 0.68‰ and 14.94 years per person, and both YPLLR (AAPC=-1.06%, t=-2.193, P=0.047) and AYLL (AAPC=-1.53%, t=-4.783, P=0.001) appeared a tendency towards a reduction, respectively. Conclusion The crude mortality of female breast cancer appeared a tendency towards a rise and the life loss appeared a tendency towards a decline in Suzhou City from 2007 to 2021. The elderly population should be given a high priority for breast cancer control.

Objective: To investigate the mortality trends and life loss due to pancreatic cancer death among residents in Suzhou City from 2006 to 2020, so as to provide insights into the management of pancreatic cancer. Methods : The data pertaining to the death of pancreatic cancer in Suzhou City from 2006 to 2020 were collected from the Jiangsu provincial mortality surveillance system. The crude mortality, standardized mortality, years of potential life lost ( YPL L), rate of YPLL ( YPLLR ), average years of life lost ( AYLL ) and annual percent change (APC) were calculated to analyze the changing trend in mortality and life loss due to pancreatic cancer. Results: The crude mortality of pancreatic cancer was 13.57/105 in Suzhou City from 2006 to 2020, appearing a tendency towards a rise ( P<0.05) with APC of 2.95%. The standardized mortality of pancreatic cancer was 6.39/105. The crude mortality of pancreatic cancer was 15.14/105 in men and 12.06/105 in women, which both showed a tendency towards a rise ( P<0.05 ) with APC of 3.18% and 2.73%. The crude mortality of pancreatic cancer appeared a tendency towards a decline in residents at ages of 30 to 45 years and 45 to 60 years ( P<0.05 ), with APC of -4.93% and -1.63%, and appeared a tendency towards a rise in residents at ages of 60 years and greater ( P<0.05 ), with APC of 0.53%. The YPLL and YPLLR of pancreatic cancer were 55 340 person-years and 0.06% in Suzhou City from 2006 to 2020, while the AYLL of pancreatic cancer was 9.81 years per person, which appeared a tendency towards a decline ( P<0.05 ), with APC of -2.35%. Conclusions The crude mortality of pancreatic cancer appeared a tendency towards a rise in Suzhou City from 2006 to 2020, and the AYLL showed a tendency towards a decline. Health education and screening of pancreatic cancer should be reinforced among men and the elderly.

This paper was aim to determine five phenolic acids, sodium danshensu (SD), protocatechuic aldehyde (PA), rosmarinic acid (RA), lithospermic acid (LA) and salvianolic acid B (SAB), in Guanxinning injection. In the test, Kromasil C18 column (4.6 mm x 250 mm, 5 µm) was adopted, with acetonitrile-3% formic acid solution as the mobile phase for gradient elution. The flow rate was 1 mL · min, the column temperature was 30 °C and the detection wavelength was 280 nm. According to the results of the test, SD, PA, RA, LA and SAB showed good linear relations between peak areas and sample sizes in 0.006 06-4.04 (r = 0.999 3), 0.006 15-4.10 (r = 0.999 4), 0.005 94-3.96 (r = 0.999 3), 0.006 06-4.04(r = 0.999 1) and 0.006 09-4.06 (r = 0.999 2) µg, respectively. The average recoveries (n = 6) were 98.9% (RSD 0.75%), 98.1% (RSD 1.2%), 100% (RSD 0.77%), 98.7% (RSD 1.7%), 102% (RSD 0.68%), respectively. The above 5 components were determined in 13 batches of samples by using the established method. The method was simple, accurate and highly reproducible that it could be used for quality control of the components in Guanxinning injection.

DNA methylation is closely related to the genesis and development of glioma.The CpG islands hypermethylation in promoter region of DNA repair genes,cell cycle controlling genes,apoptosis related genes,tumor suppressor genes and invasion related genes are found in glioma.Finding the specific methylation profile and molecular marker of glioma is helpful for the pathology class,early diagnosis and prognostic evalua-tion.Meanwhile,DNA methylation has the characteristic of reversibility,which may provide new ways for the treatment of glioma.
