Objective:
To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases.
Methods:
A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases.
Results:
The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease.
Conclusion
The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.

OBJECTIVETo measure the iodine nutritional status on adult islanders and to evaluate the advantages and disadvantages of iodized salt prophylactic programs.
METHODSA comparative study was carried out in 8 rural townships selected from Dinghai (iodized salt district) and Daishan (non-iodized salt district) of Zhoushan islands by random sampling method. Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake of the two groups. Spearman correlation test was used to look for the correlation of urinary iodine concentration and dietary iodine intake in the two groups respectively.
RESULTSThe amounts of daily iodine intake excluding the iodine intake from iodized salt in the two groups were 128 micro g and 147 micro g respectively but the difference was not statistically significant (u = 1.847, P = 0.065). The urinary iodine concentration of non-iodized salt group was 90 micro g/L, lower than 194 micro g/L in iodized salt group (u = 14.673, P = 0.000). There was no significant correlation between daily iodine intake and urinary iodine concentration (r(s) = 0.052, P = 0.095).
CONCLUSIONSIn Zhoushan islands, the daily iodine intake did not meet the daily need (150 micro g/day) suggesting that iodized salt supplement was necessary. However, side effect due to overdose should be brought into attention.

OBJECTIVETo investigate the efficacy of the Chinese medicine Huzhangdanshenyin on male immune infertility, and provide an effective therapy for this disease.
METHODSNinety men with immune infertility were selected as the research subjects and randomly divided into two groups, 60 in the treatment group, treated by Huzhangdanshenyin, and the other 30 in the control, treated by prednisone, both for 3 months. The improvement of clinical symptoms, immunologic indexes (antisperm antibodies in serum and seminal plasma) and sperm indexes (semen liquefied duration, motility, viability, density and abnormal morphology rate) were observed and the results analyzed.
RESULTSThe total antisperm antibody reversing ratio of the treatment group was higher than that of the control (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms were lower (P < 0.01), and the improvement of the clinical symptoms was better in the treatment group than in the control (P < 0.01), especially the symptoms of pain in the back and knees, distending and bearing-down sensation of the perineum and testis, hypersexuality and topalgias. Compared with pre-treatment, sperm motility and viability of the treatment group significantly improved (P < 0.01), and so did sperm density (P < 0.05). However, there were no significant differences in sperm density, semen liquefied duration, abnormal morphology rate and pH (P > 0.05) before and after the treatment.
CONCLUSIONThe Chinese medicine Huzhangdanshenyin works more effectively than prednisone in the treatment of male immune infertility. It could improve the antisperm antibody reversing ratio, clinical symptoms and signs and ameliorate sperm indexes with no obvious advierse effects.

AIMTo analyze the ginsenosides in Kou zi qi (rhizomes of Panax japonicus C. A. Mey. var. major (Burkill) C. Y. Wu et K. M. Feng), and to supply evidences for chemotaxanology of Panax species and clinical uses of Kou zi qi.
METHODSThe ginsenosides were isolated by HPLC, then the positive- and negative-ion API-MS/MS of constituents collected from HPLC were measured.
RESULTSEight ginsenosides were identified as ginsenoside Re, ginsenoside Ro, chikuseksusaponins IV, IVa, notoginsenoside R2, ginsenosides Rb1, Rc and Rd, respectively, based on comparison of retention time with those of standards by HPLC, and analysis on their API-MS/MS data. Ginsenoside Ro and chikuseksusaponin IVa are the major components of Kou zi qi.
CONCLUSIONThis plant had a close relationship to P. stipuleanatus, P. zinginensis and P. japonicus var major; a relatively remote relationship to P. ginseng and P. quinquefolius, in a view of chemotaxanology. Ginsenoside Ro and chikuseksusaponin IVa might be the anti-inflammatory constituents of Kou zi qi.
