Objective:To analyze the changes in the disease burden of prostate,testis,kidney and bladder cancers among uri-nary and reproductive system tumors in Chinese men from 1990 to 2019 with a prediction of the future trend.Methods:We re-trieved the data on the incidence,mortality and disease burden of prostate,testis,kidney and bladder cancers in Chinese men between 1990 and 2019 from the database of Global Burden of Disease Study 2019.Using the Joinpoint regression model,we analyzed the trend of changes in the disease burden,and predicted the prevalence of the tumors with the ARIMA model.Results:From 1990 to 2019,the standardized incidence and prevalence of prostate,testis,kidney and bladder cancers were on the rise in Chinese men,and those of testis cancer increased most significantly,by 326.79% and 1070.93% respectively.The disease burden of PCa was the highest,with standardized incidence,prevalence and mortality ratios of 17.34/100 000,117.65/100 000 and 7.79/100 000 respectively in 2019.The standardized mortality and disability-adjusted life years(DALY)of kidney cancer were increased by 103.59% and 103.17% respectively.The highest incidence,mortality and DALY of prostate,kidney and bladder cancers in 2019 were found in 90-94 years old males,the highest prevalence rates of prostate,kidney and bladder cancers in the 70-89-year-olds,and the highest prevalence of testis cancer in the25-49-year-olds.ARIMA model prediction showed that the standardized incidence rates of prostate,testis,kidney and bladder cancers in Chinese men kept rising from 2020 to 2029.Conclusion:The disease burden of prostate,tes-tis,kidney and bladder cancers in Chinese men is on the rise,and their standardized incidence rates will be even higher by 2029,with a significant increase in the disease burden in young men,which suggests the need of more attention to the prevention and treatment of genitourinary system tumors in young males.

Objective To search for application ways for the safe and effective clinical methods of arsenic-containing Compound Qinghuang Powder (Compound QHP) for the treatment of myelodysplastic syndrome (MDS). Methods Totally 200 patients with MDS were included in the study and treated with Compound QHP. After one-month treatment, the 60 patients with the blood arsenic concentrations <20 μg/L were randomly divided into control group and treatment group, with 30 cases in each group. Control group was given stable treatment, while the treatment group was given increased dose of realgar; blood arsenic concentration was detected monthly; realgar 0.1 g was increased each time until blood arsenic concentrations ≥20 μg/L and realgar ≤0.3 g/d. The blood arsenic concentration, clinical efficacy and safety in the two groups were observed. Results Totally 24 cases in each group were included for evaluation finally. The average blood arsenic concentration of treatment group was significantly higher than those of control group (P<0.05). The rate of hematologic improvement was significantly higher in treatment group (54.2％, 13/24) than that in control group (29.2％, 7/24) , with significant difference (P<0.05). The Hb, ANC, and PLT significantly increased in treatment group after treatment (P<0.05). There was no significant difference of incidence rate of adverse reaction observed between treatment group and control group (P>0.05). Conclusion In application of Compound QHP, the blood arsenic concentration can be monitored to adjust the daily dose of realgar, thus to increase the effective blood arsenic concentration, and then improving efficacy without increasing the clinical toxicity.

Objective To analyze the clinical efficacy and safety of compound Qinghuang powder (compound QHP) for treatment of myelodysplastic syndromes (MDS) and its association with blood arsenic concentration (BAC). Methods 40 patients with MDS were treated with compound QHP, and the clinical efficacy, safety, and its association with BAC were evaluated after treatment for 6, 9 months, respectively. Results After treatment for 6 months, the rate of hematology improvement was 32.5 % (13/40), and the effective rate was 87.5%(35/40). 21 cases depended on the blood transfusion before treatment, after treatment 6 cases completely got rid of blood transfusion and the blood transfusion of another 6 cases was decreased by more than 50 %. The absolute neutrophil count was increased from (0.50±0.13)×109/L to (0.93±0.33)×109/L (t= 4.130, P= 0.0008). The hemoglobin content was increased from (71.06±14.82) g/L to (80.41±27.35) g/L (t= 2.233, P= 0.0321). After treatment for 9 months, 76.2 % (16/40) of the patients got rid of blood transfusion or blood transfusion reduction was more than 50%. The platelet count was increased from (45.04 ± 24.38)×109/L to (60.65±29.46)×109/L (t= 2.241, P= 0.0335). The incidence of abdominal pain and diarrhea after treatment for 1, 3 and 6 months were 12.5 % (5/40), 10.0 % (4/40) and 5.0 % (2/40), respectively, all belonging to mild level . Before treatment , there were 12 patients with abnormal liver function , including 6 cases back to normal after treatment, and 6 cases of significantly relieved, without new case with abnormal liver function. Before treatment, there were 10 cases with abnormal myocardial enzymes, including 1 cases back to normal after treatment and 9 cases significantly relieved, without new case with abnormal myocardial enzymes. No patient with abnormal renal function was observed before and after treatment. The BAC was (7.71±5.65) μg/L before treatment, which was significantly lower than that of 1, 3 and 6 months [(29.27±9.07)μg/L, (27.79 ±10.18) μg/L and (31.98 ±12.55) μg/L respectively, all P< 0.0001]. There was no significant change of BAC among the patients after treatment for 1, 3 and 6 months (P> 0.05). The BAC in efficacy group [(33.48 ±12.56) μg/L] was significantly higher than that in non-efficacy group [(21.46 ±6.00) μg/L] (t=2.089, P=0.035). 12.5% (5/40) of the patients had mild gastrointestinal side effects after treatment for 1 month, while the BAC of them [(16.93 ±1.80) μg/L] was significantly lower than that in patients without gastrointestinal side effects [(31.78±1.39 ) μg/L, P<0.0001]. The occurrence rate of abdominal pain and diarrhea was decreased after treatment for 3 and 6 months, while the BAC was increased gradually. Conclusions Compound QHP is effective in the treatment of MDS with mild adverse reactions. There is no damage to the heart, liver, and renal function. Besides, it shows that reducing the gastrointestinal adverse reactions and maintaining the effective concentration of BAC play a significant role in the effect of compound QHP in the treatment of MDS.

OBJECTIVE To explore the neuro-protective effects of saffron (Crocus satius L.) on chronic focal cerebral ischemia in rats.METHODS SD rats were randomly divided into 6 groups:sham control group,MCAO group,edaravone group and saffron 30,100,300 mg·kg-1groups.Focal cerebral ischemia was induced by middle cerebral artery occlusion(MCAO).Saffron was administered orally by once daily from 2 h to 42 d after ischemia. At 42 d after cerebral ischemia, neurological deficit score, spontaneous activity test,elevated plus maze test,marble burying test and novel objective recognition test were used to evaluate the effects of saffron on the behevioural change. Infarct volume, survival neuron density, activated astrocyte number, and the thickness of glial scar were also detected. GFAP expression and inflammatory cytokine contents in ischemic peripheral region were detected by Western blot and ELISA,separately.RESULTS Saffron(100,300 mg·kg-1)improved the body weight decrease, neurological deficit and spontaneous activity. Saffron (30-300 mg·kg- 1) increased the traveled distance ratio and total time in open arm, decreased the buried marble number, which indicated that saffron could ameliorate anxiety- and depression-like behaviors. Saffron (100, 300 mg·kg-1)improved the learning and memory function,which manifested by increased discrimination ratio(DR)and discrim-ination index (DI) in T2test. The results of toluidine blue found saffron treatment (100, 300 mg·kg-1) decreased the infarct volume and increased the neuron density in cortex and hippocampal.The activated astrocyte number,the thickness of glial scar and GFAP expression in ischemic peripheral region decreased after saffron. Saffron (100, 300 mg·kg-1) decreased the contents of IL-6 and IL-1β, increased the content of IL-10 in ischemic peripheral region.CONCLUSION Saffron exerted neuro-protective effects on chronic focal cerebral ischemia,which could be related with inhibiting the activation of astrocyte and glial scar,following with the decrease of inflammatory reaction.

OBJECTIVETo investigate the risk factors for recurrent wheezing in infants and young children suffering from dust mite allergy after their first wheezing.

METHODSA total of 1 236 infants and young children who experienced a first wheezing episode and were hospitalized between August 2014 and February 2015 were enrolled, among whom 387 were allergic to dust mites. These infants and young children were followed up to 1 year after discharge. A total of 67 infants and young children who experienced 3 or more recurrent wheezing episodes within 1 year were enrolled as the recurrent wheezing group, while 84 infants and young children who did not experience recurrent wheezing during follow-up were enrolled as the control group. Univariate analysis and multivariate logistic stepwise regression analysis were performed to investigate the risk factors for recurrent wheezing in these patients.

RESULTSThe univariate analysis showed that the age on admission, wheezing time before admission, Mycoplasma pneumoniae infection rate, and influenza virus infection rate were associated with recurrent wheezing. The multivariate logistic stepwise regression analysis showed that the older age on admission (OR=2.21, P=0.04) and Mycoplasma pneumoniae infection (OR=3.54, P=0.001) were independent risk factors for recurrent wheezing.

CONCLUSIONSInfants and young children who are allergic to dust mites, especially young children, have a significantly increased risk of recurrent wheezing if they are complicated by Mycoplasma pneumoniae infection during the first wheezing episode.

Systemic chemotherapy is the basic palliative treatment for metastatic nasopharyngeal carcinoma (NPC); however, it is not known whether locoregional radiotherapy targeting the primary tumor and regional lymph nodes affects the survival of patients with metastatic NPC. Therefore, we aimed to retrospectively evaluate the benefits of locoregional radiotherapy. A total of 408 patients with metastatic NPC were included in this study. The mortality risks of the patients undergoing supportive treatment and those undergoing chemotherapy were compared with that of patients undergoing locoregional radiotherapy delivered alone or in combination with chemotherapy. Univariate and multivariate analyses were conducted. The contributions of independent factors were assessed after adjustment for covariates with significant prognostic associations (P < 0.05). Both locoregional radiotherapy and systemic chemotherapy were identified as significant independent prognostic factors of overall survival (OS). The mortality risk was similar in the group undergoing locoregional radiotherapy alone and the group undergoing systemic chemotherapy alone [multi-adjusted hazard ratio (HR) = 0.9, P = 0.529]; this risk was 60% lower than that of the group undergoing supportive treatment (HR = 0.4, P = 0.004) and 130% higher than that of the group undergoing both systemic chemotherapy and locoregional radiotherapy (HR = 2.3, P < 0.001). In conclusion, locoregional radiotherapy, particularly when combined with systemic chemotherapy, is associated with improved survival of patients with metastatic NPC.

Objective: To understand the HIV and syphilis infection and related treatment status of low-fee female sex workers (FSWs) in 3 provinces of China. Methods: Four cross-sectional survey data of low-fee FSWs from six cities (counties) in Guangxi, Yunnan and Hunan Province between October 2012 and July 2015 were obtained from the national science and technology major special project intervention study for reducing sexually transmitted diseases (STDs) and acquired immunodeficiency syndrome (AIDS) in low-fee FSWs' database, which included social demographic characteristics, sexual service characteristics and related medical care seeking behaviors, etc. A total of 2 050 subjects were included in the database. Results: The age of the subjects was (35.16±9.76) years old, with a minimum age of 15 and a maximum age of 67. Those who use condoms every time in commercial sex accounted for 58.9% (n=1 206). Among the reasons of not using condom, the proportion of client reluctant to use was the highest (81.0% (n=682)). Only 38.1% (n=782) was tested for HIV in the last six months. HIV confirmed positive rate was 6.8% (n=139), previous positive accounts for 76.3% (n=106). Rate of antiviral therapy was 55.4% (n=77). By the end of 2015, the loss rate of antivirus treatment was 18.2% (n=14). Those who self-reported symptoms of sexually transmitted diseases in the last 6 months accounted for 9.4% (n=191). 50.3% (n=96) of reporters chose to go to formal hospitals, 23.0% (n=44) chose to go to private clinics and 20.4% (n=39) chose their own medication. The syphilis infection rate was 13.5% (n=277), among them, 91.3% (n=253) were asymptomatic. Conclusion Among low-fee FSWs, the rates of HIV and syphilis infection are higher, the condom consistent use rate, HIV antibodies and syphilis test rate are lower. In this group, active seeking medical idea is poor, the rate of anti-virus treatment and the rate of seeking medical treatment in formal medical institutions is low.

OBJECTIVE: To observe the regulative effect of Tongdu Tiaoshen acupuncture on the depression-like behavior and cAMP-response element binding protein (CREB)/brain-derived neurotrophic factor (BDNF)/tyrosine protein kinase B (TrkB) signaling pathway of hippocampus in rats with post-stroke depression (PSD), and to explore its possible mechanism on improving PSD. METHODS: A total of 36 SPF SD rats were randomized into a sham operation group, a model group and a Tongdu Tiaoshen group, 12 rats in each group. The compound method of Zea Longa suture-occlusion and chronic unpredictable mild stress (CUMS) was used to establish the PSD model in rats of the model group and the Tongdu Tiaoshen group. On the 4th day after modeling, acupuncture was applied at "Dazhui" (GV 14), "Shuigou" (GV 26), "Baihui" (GV 20) and "Shenting" (GV 24) in the Tongdu Tiaoshen group, 40 min every time, once a day, 6 times a week for 4 weeks consecutively. On the 2nd day after PSD modeling and after 4-week intervention, Zea Longa neurobehavioral score was evaluated, sucrose water consumption test and open-field test were performed; biochemical method was used to detect the SOD, CAT activity and MDA level in hippocampal CA1 area; ELISA method was used to detect the serum level of BDNF; real-time PCR was used to detect the mRNA expression of BDNF, TrkB and CREB in hippocampal CA1 area; Western blot was used to detect the protein expression of BDNF, TrkB, CREB and p-CREB in hippocampal CA1 area. RESULTS: Compared with the sham operation group, Zea Longa neurobehavioral scores were increased (P<0.05), percentage of sucrose water consumption, horizontal motion and vertical motion scores of open-field test were decreased after modeling and intervention in the model group and after modeling in the Tongdu Tiaoshen group (P<0.05). Compared with the model group, Zea Longa neurobehavioral score was decreased (P<0.05), percentage of sucrose water consumption, horizontal motion and vertical motion scores of open-field test were increased after intervention in the Tongdu Tiaoshen group (P<0.05). Compared with the sham operation group, the SOD and CAT activity in hippocampal CA1 area and serum level of BDNF were decreased (P<0.05), MDA level in hippocampal CA1 area was increased in the model group (P<0.05); compared with the model group, the SOD and CAT activity in hippocampal CA1 area and serum level of BDNF were increased (P<0.05), MDA level was decreased in the Tongdu Tiaoshen group (P<0.05). Compared with the sham operation group, the mRNA expression of BDNF, TrkB and CREB as well as the protein expression of BDNF, TrkB, CREB and p-CREB were decreased in hippocampal CA1 area in the model group (P<0.05); compared with the model group, the mRNA expression of BDNF, TrkB and CREB, the protein expression of BDNF, TrkB and p-CREB as well as the ratio of p-CREB/CREB were increased in the Tongdu Tiaoshen group (P<0.05). CONCLUSION Tongdu Tiaoshen acupuncture can improve the depression-like behavior in PSD rats, the mechanism may be related to the inhibition of oxidative stress in hippocampal tissues and the enhanced activity of CREB/BDNF/TrkB signaling pathway.

OBJECTIVE: To investigate the relation of blood arsenic concentration (BAC) with clinical effect and safety of arsenic-containing Qinghuang Powder (, QHP) in patients with myelodysplastic syndrome (MDS). METHODS: Totally 163 patients with MDS were orally treated with QHP for 2 courses of treatment, 3 months as 1 course. The BACs of patients were detected by atomic fluorescence spectrophotometry at 1, 3, and 6 months during the treatment, and the effective rate, hematological improvement and safety in patients after treatment with QHP were analyzed. RESULTS: After 2 courses of treatment, the total effective rate was 89.6% (146/163), with 31.3% (51/163) of hematological improvement and 58.3% (95/163) of stable disease. The hemoglobin increased from 73.48 ± 19.30 g/L to 80.39 ± 26.56 g/L (P<0.05), the absolute neutrophil count increased from 0.81 ± 0.48 × 10/L to 1.08 ± 0.62 × 10/L (P<0.05), and no significant changes were observed in platelet counts (P>0.05). Among 46 patients previously depended on blood transfusion, 28.3% (13/46) completely got rid of blood transfusion and 21.7% (10/46) reduced the volume of blood transfusion by more than 50% after treatment. The BACs were significantly increased in patients treated for 1 month with 32.17 ± 18.04 μ g/L (P<0.05), 3 months with 33.56 ± 15.28 μ g/L (P<0.05), and 6 months with 36.78 ± 11.92 μ g/L (P<0.05), respectively, as compared with those before treatment (4.08 ± 2.11 μ g/L). There were no significant differences of BACs among the patients treated for 1, 3 and 6 months (P>0.05). The adverse reactions of digestive tract during the treatment were mild abdominal pain and diarrhea in 14 cases (8.6%), and no patients discontinued the treatment. The BACs of patients with gastrointestinal adverse reactions were significantly lower than those without gastrointestinal adverse reactions (22.39 ± 10.38 vs. 37.89 ± 11.84, μ g/L, P<0.05). The BACs of patients with clinical effect were significantly higher than those failed to treatment (40.41 ± 11.69 vs. 23.84 ± 12.03, μ g/L, P<0.05). CONCLUSION QHP was effective and safe in the treatment of patients with MDS and the effect was associated with BACs of patients.
