ABSTRACT
Objective:To investigate the efficacy and safety of black tomato concentrated sauce in the treatment of benign prostatic hyperplasia(BPH) with lower urinary tract symptoms(LUTS).Methods:An open, randomized and controlled trial was conducted, and 150 BPH patients with LUTS were randomly assigned to three groups: experimental group(60 cases), placebo group (45 cases) and positive control group(45 cases) in the Department of Urology, Lanzhou University Second Hospital from December 2018 to September 2020.Inclusion criteria: age≥50 years old; first diagnosis of BPH, or interrupted medical treatment of BPH for more than 1 month; maximum urinary flow rate (Q max) <15ml/s; prostate volume (PV)≥20ml; IPSS≥8, QOL≥2. Exclusion criteria: lower urinary tract obstruction not caused by BPH, post-void residual urine volume(PVR) >250 ml; history of acute urinary retention in the last 3 months; prostate nodules and suspected prostate cancer were revealed by digital rectal examination and transrectal B-ultrasoundor; prostate-specific antigen (PSA)≥10 ng/ml; neurogenic bladder, perivous history of bladder, prostate, or urethra operations; suffering from serious heart, lung, liver, kidney and other diseases. The patients in the experimental group were orally treated with black tomato concentrated sauce(30 g/once, 3 times/day). The patients in the placebo group were orally administrated with placebo. In the positive control group, the patients with PV≤30ml were orally treated with tamsulosin(0.2mg/once, 1 time/day), the patients with PV>30ml were orally administrated with tamsulosin and finasteride(5 mg/once, 1 time/day). All enrolled patients were treated for 3 months. At the end of third month, the IPSS, QOL, PV, PVR, Q max, average urinary flow rate(Q ave), total PSA(tPSA), free PSA (fPSA), testosterone(TST) and the incidence of adverse reaction were assessed. Results:128 of 150 cases, including 52 cases in experimental group, 36 cases in placebo group and 40 cases in positive control group, completed the study, the rest was excluded due to not take medication regularly and fail to follow-up. There were no significant differences in baseline parameters among experimental group, placebo group and positive control group ( P>0.05) in age[(63.21±8.61) vs.(62.36±6.32) vs. (63.94±7.78)years old], body mass index[(23.74±3.17) vs. (23.94±3.09) vs. (24.26±2.91)kg/m 2], IPSS[(17.5±6.6) vs. (15.4±5.8) vs. (17.9±6.8)], QOL[4.0(3.0, 4.0) vs. 4.0(3.0, 4.5) vs. 4.0(3.0, 5.0)], Q max [(8.60±3.04) vs. (9.13±2.92) vs. (9.58±3.26) ml/s], Q ave[(4.39±1.69) vs. (4.66±1.76) vs. (4.88±1.60)ml/s], PV [32.00(25.55, 45.40)vs. 30.00(24.45, 38.35)vs. 34.80(27.65, 56.65)ml], PVR[23.50(8.25, 45.75) vs.5.50(0, 47.75) vs. 29.00(0, 84.00)ml], tPSA [1.53(0.89, 3.00) vs. 1.23(0.69, 1.98) vs. 2.23(0.90, 4.15)ng/ml], fPSA [0.37(0.28, 0.76) vs. 0.37(0.22, 0.52) vs. 0.54(0.30, 0.97) ng/ml] and TST[(443.64±156.32) vs. (493.97±176.16) vs. (450.89±135.08)ng/dl]. After 3 months of treatment, the IPSS in experimental group was(9.9±5.7), QOL score 2.0(2.0, 3.0), Q max(11.78±5.24)ml/s, Q ave(5.86±3.00)ml/s, tPSA 1.64(0.96, 3.32)ng/ml and TST (475.91±177.33)ng/dl, which were significantly different compared with pre-treatment( P<0.05). In positive control group, IPSS was (9.0±6.2), QOL 2.0(2.0, 3.0), Q max(11.73±4.50)ml/s, Q ave(6.11±2.53)ml/s, tPSA 1.57(0.80, 3.09)ng/ml, fPSA 0.37(0.24, 0.63)ng/ml and TST (526.11±126.88)ng/dl, which were statistically different compared with pre-treatment( P<0.01). However, there were no significant differences in all the above indexes in placebo control group compared with the baseline( P>0.05). The numerical changes of IPSS, QOL, Q maxand Q ave between experimental group and placebo group had statistically significant differences ( P<0.05). The changes of IPSS, QOL, Q max, Q ave, PV, tPSA, fPSA and TST between positive control group and placebo group had significant differences ( P<0.05). The changes of PV, tPSA and fPSA between positive control group and experimental group had statistically significant differences ( P<0.05). The incidence of adverse reactions was 5.77% (3/52, including 1 headache and 2 stomach discomfort) in experimental group, 5.56% (2/36, including 1 headache and 1 stomach discomfort) in placebo group, and 10.00%(4/40, including 1 dizzy, 1 nasal obstruction and 2 erectile dysfunction) in positive control group. And there was no statistical difference in the incidence of adverse reactions among three groups ( P>0.05). Conclusions:Black tomato concentrated sauce shows an excellent effect on patients with LUTS/BPH, and improves the quality of life with few adverse events.
ABSTRACT
OBJECTIVE@#To study the inhibitory effect of pills (BJJ) agaisnt diethylnitrosamine (DEN)-induced hepatocarcinogenesis and explore the relation between this effect and the inflammasome signaling pathway.@*METHODS@#Sixty-five male SD rats were randomly divided into control group, DEN model group, and 3 BJJ treatment groups at low, medium and high dose (with daily dose of 0.55, 1.1 and 2.2 g/kg, respectively, for 12 consecutive weeks starting from the 5th week after modeling). The pathological changes of the liver tissue were observed with HE and Masson staining, and serum levels of alanine transaminase (ALT), glutamic oxaloacetic transaminase (AST), alkaline phosphatase (ALP) and total bilirubin (TBIL) of the rats were detected using ELISA. Oxidation stress in the liver tissue was assessed with ELISA, and Western blotting and ELISA were used to detect the molecular expressions of inflammasome-related pathway.@*RESULTS@#BJJ significantly inhibited tumor growth in the liver of the rats. HE and Masson staining showed that BJJ treatment obviously ameliorated liver fibrosis and reduced cancer cell and inflammatory cell infiltration in the liver. BJJ significantly reduced elevations of serum ALT, AST, ALP and TBIL levels, increased the contents of superoxide dismutase, catalase and glutathione peroxidase in the liver and suppressed malondialdehyde in Den-treated rats. BJJ also dose-dependently decreased the expressions of NLRP3, apoptosis-associated speck-like protein (ASC), caspase-1, pro-IL-1β, pro-IL-18, IL-1β and IL-18 in the liver of Den-treated rats.@*CONCLUSIONS@#BJJ treatment can dose-dependently inhibit DEN-induced hepatocarcinogenesis by enhancing antioxidant capacity and down-regulating inflammatory-related pathways in rats.

Objective To investigate medication adherence and its influencing factors in community-based hypertensive patients in the Pearl River Delta of Guangdong Province, and lay the foundation for the development of targeted compliance interventions. Methods Between July 2015 and October 2016, a multi-stage cluster sampling method was used to conduct a community-based diagnostic survey in the Pearl River Delta region.A total of 1 829 community-based hypertension patients in this survey population were used to investigate medication adherence, the factors of which were derived through a multi-factor logistics regression analysis.Results The average medication-adherence score of hypertensive patients surveyed in this study was (4.6 ± 1.8), and patients with good medication adherence accounted for 62.82%(1 149/1 829).There were significant differences in medication adherence among patients according to their age, household registration types, marital status, level of education, employment status, medical payment methods,per capita monthly household income,drinking status,and family history of hypertension (P<0.05).Multivariate logistic regression analysis found that medication adherence was affected substantially by the type of household registration:local household types (OR= 0.537, 95% CI: 0.415-0.695); education level: college,bachelor and above (OR=2.139,95% CI:1.100-4.160); employment status: self-paying (OR=0.591, 95% CI: 0.376-0.930); and a family history of hypertension (OR= 1.279, 95% CI: 1.012-1.617).Conclusions It is necessary to pay more attention to medication adherence in patients with hypertension in communities.Given the influencing factors and characteristics illuminated by this study,it is suggested that various measures be taken to prevent and intervene in poor medication adherence, to improve the curative effect of hypertensive patients in communities.
ABSTRACT
Objective:To explore the microRNA profile changes in the development of NKT cells.Methods: Differently developmental stage of NKT cells in mouse thymus were sorted by flow cytometry.Total RNA were extracted,reversely transcribed and pre-amplified.TaqMan low density microRNA assay and single real-time PCR were applied to detect the expression changes of microRNAs in the developmental process of NKT cells.Results: There were total 92 microRNAs whose expression changed significantly during the development and maturation of NKT cells.Among them,increasly expressed microRNAs were 71,including 36 microRNAs whose expression continuously increased;decreasly expressed microRNAs were 21,including 12 microRNAs whose expression continuously decreased.In addition,single real-time PCR analysis showed that the expression of Let-7f,miR-150,miR-24,miR-29 increased,while the expression of miR-223 and miR-155 decreased during the development and maturation of NKT cells.Conclusion: NKT development and maturation is accompanied by expression changes of large amount of microRNAs,indicating that specific microRNA regulates NKT development and function.
ABSTRACT

Cardiovascular disease caused by hypertension has become the first cause of death of residents in our country, the burden of disease has become more and more serious, how to manage hypertension has become an important public health issue in our country. In this review, the development and current situation of the community health management of hypertension at home and abroad are described and analyzed, the experience and practice worthy of learning are summarized to provide evidence for the prevention and control of hypertension in community.
ABSTRACT
Objective To survey village doctors'knowledge,demand and behavior of health management,to provide scientific evidence for village people's health self-management.Methods Prepared a self-designed question-naire and make it completed by 106 village doctors chosen at random from 106 different villages in the eight towns in Guangzhou's two mountainous districts.Results The average age of the village doctors was(50.9 1 ±7.84)years, 36.79% of them had the ultimate diploma of a health technical school,and the average knowledge rate of health man-agement was 30.09%.There was remarkable difference among the 3 age groups which disclosed statistic value(χ2 =112.900,P =0.000).The 35-44 age group was the highest in the knowledge rate of health management (52.61%). The doctors with a ultimate technical diploma vary in the knowledge rate (the highest was 47.44%),which also had statistic value(χ2 =112.900,P =0.000).Only 2.83% of the village doctors believed that their health management skill can completely meetthe current demand and 3.77% can.18.87% believed that training about health management was very meaningfuland 25.47% meaningful.63.21% (most required by the health bureau) expected to receive training.16.98% didn't receive such training in the recent year because they thought it was un-necessary or not available.11.32% of the village doctors were willing to pay for the health management training,while 97.17% had never taken such training on their own expenses.Conclusion Village doctors are mostly elderly,low-educated,and insufficient in the professional knowledge of health management.Without the corresponding motivations and regulations,they are not enthusiastic about the training.It is suggested that the local authorities pay more attention to the buildup of the village health stations and improve the structure,knowledge,and earning of the village doctor group so as to ensure the effective health management service for the masses in villages.
ABSTRACT
Objective To understand the short-term effect of practice skill training for general practitioners in Guangdong province and to provide scientific basis for improving the training strategy. Methods According to the training outline (Outline of job-transfer training for general practitioner in primary health institutions (trial))of the Ministry of Health,job-transfer training was provided for a total of 451 primary care doctors in economically undeveloped cities for one year. All trainees were investigated before and after training by questionnaire,which were designed by ourselves and included practical skill level and satisfaction degree.SPSS 13.0 software was used to do statistical analysis and data were processed by description analysis,t test,ANOVA and correlation analysis. Results Average self-evaluation scores of practical skills were 136.37 ±21.74 and 169.39 ±17.12 before and after training with significant differences (t=29.028,P=0.000). Scores of all types of practical skills after training were significantly higher than those before training (P<0.000 1). Total satisfaction rate was 91.6%and students were not well satis-fied with training environment and training guarantee. Fac-tors influencing the effect of training included educational background,professional title,doctors' de-sire of training,whether taking part in the general practitioner training or not. The effect of practical training was positively correlated with total satisfaction (r=0.162,P=0.037). Conclusions Remark-able results of practice skill training have been achieved. In the future,more chances for practice should be provided for trainees and contents of skill training should be designed according to the need of community health service,and more attention should be paid to the training project management.

ABSTRACT
Preventing and curing emergency infectious diseases,such as A H1N1 influenza,is a public health practice,and its relevant ethical problems are pubic health ethical problems,mainly manifesting as the conflicts between individual interests and public interests,individual freedom and quarantine,individual privacy right and releasing partial medical information,and choosing one's own doctors and compulsory treatment.The core of the issue is that individual interests should be submitted to the public interests,and at the same time government and society should respect individual's freedom,privacy and right of health.
