AIM: To gain an insight into preference for elderly diabetic patients with angina pectoris between Shexiang Baoxin Pill (SXBXP) (Moschus, Radix Ginseng, Calculus Bovis, etc.) and Extended Release Isosorbide 5-Mononitrate (ERIM). METHODS: Followed a two-week run-in, 56 elderly patients were randomized to take SXBXP 2 pills tid or ERIM 60 mg qd for 4 weeks; then followed a two-week wash-out, patients crossed over to the complementary therapy for another 4 weeks. Daily diary cards were used to record the side effects, the frequency of angina pectoris attacks and use of rescue medication. At the end of the study, participants were asked to complete a 3-item scale questionary to assess their angina pectoris treatment in terms of convenience, side effects and overall preference. RESULTS: No treatment difference in the frequency of angina pectoris attacks and use of rescue medication was found; 71.4% of patients thought use of SXBXP was the same convenient as that of ERIM; patients felt SXBXP had side effects fewer than ERIM and overall 75% of patients preferred SXBXP. CONCLUSION: Elderly diabetic patients with angina pectoris prefer SXBXP to ERIM.

Objective To investigate the effectiveness and cost of 50% and 80% wettable powder of niclosamide ethanolamine salt (NESWP) and 26% metaldehyde and niclosamide suspension concentrate (MNSC) in hilly schistosomiasis-endemic regions, so as to provide insights into the selection of chemical molluscicides in hilly regions. Methods In September 2020, a wasteland in Guanshanqiao Village, Yanrui Township, Yushan County of Jiangxi Province was selected as the experimental region, which was sectioned into five blocks and defined as four experimental groups (A1, A2, B, C) and a blank control group (D). 80% NESWP were given at doses of 1 g/m2 and 1.5 g/m2 in groups A1 and A2 using the spraying method, 50% NESWP was given at a dose of 2 g/m2 in Group B using the spraying method, and 26% MNSC was at a dose of 4 g/m2 in Group C using the spraying method, while no chemical treatment was given in Group D. Snail survey was performed using a systematic sampling method before chemical treatment and 1, 3, 7 d and 15 d post-treatment to examine the molluscicidal effect, and all molluscicidal costs were estimated to calculate the cost of chemical treatment per 1 m2 and the cost of the reduction in the mean density of living snails per 1%. Results The highest mortality of snails was 78.95% and the lowest density of living snails was 0.2388 snails/0.1 m2 in the experimental groups within 7 d of chemical treatment, and the highest mortality of snails was 94.74% and the lowest density of living snails was 0.058 0 snails/0.1 m2 7 d post-treatment. There were no significant differences in the snail mortality among the A1, A2, B and C groups 1 (χ2 = 2.250, P > 0.05), 3 (χ2 = 1.779, P > 0.05) or 15 d post-treatment (χ2 = 2.286, P > 0.05), while a significant difference was detected in the snail mortality among the four groups 7 d post-treatment (χ2 = 7.990, P = 0.046). In addition, there were no significant differences in the snail mortality between A1 and A2 groups 1 (χ2 = 0.724, P > 0.05), 3 (χ2 = 0.584, P > 0.05), 7 (χ2 = 0.400, P > 0.05) or 15 d post-treatment (χ2 = 0.251, P > 0.05). The costs of chemical treatment per 1 m2 were 0.58, 0.60, 0.64 Yuan and 0.73 Yuan in groups A1, A2, B and C, and the costs of the mean density of living snail per 1% reduction were 19.29, 20.44, 21.68 Yuan and 23.53 Yuan in groups A1, A2, B and C, respectively. Conclusion 80% NESWP shows a high molluscicidal efficacy and low cost in hilly schistosomiasis-endemic regions.

BACKGROUND:Apoptosis of islet cel s is closely related to the long-term hyperglycemia-and hyperlipemia-induced injuries. OBJECTIVE:To observe the effect of Shizidaiping formula on the apoptosis and insulin secretion in MIN6 cel s under the high glucose and lipid environment, and to explore the protective effect of Shizidaiping formula and the related apoptosis mechanism. METHODS:MIN6 cel s were divided into normal, model, melbine, low-, medium-and high-dose Shizidaiping formula groups. The cel activity was examined by cel counting kit-8, the insulin secretion was measured by ELISA, the rate of apoptosis was measured by Annexin V-FITC&PI and the expression levels of MEK1/2, ERK1/2 and p-ERK1/2 were examined by western blot assay. RESULTS AND CONCLUSION:Shizidaiping formula significantly improved MIN6 cel activity under high glucose and lipid condition (P<0.05), decreased early cel apoptosis, increased the level of insulin stimulated by low glucose in cel supernatant (P<0.05), and improved the expression levels of MEK1/2, ERK1/2 and p-ERK1/2 (P<0.05). These results suggest that Shizidaiping formula can protect islet cel s from hyperglycemia and hyperlipemia damage by improving the activity of MIN6 cel s, reducing the insulin secretion and inhibiting the apoptosis of pancreaticβcel s in MIN6 cel s.

Objective:
To construct the Z-score models for normal fetal brain fissures.
Methods:
Four hundred and eighty-seven pregnant woman who underwent prenatal ultrasonography from January to August 2018 in the Second Xiangya Hospital of Central South University were collected randomly for analysis, and all the fetuses(18-38 weeks) were healthy. The calacarine fissure, pariet-ooccipital fissure, sylvian fissure of the fetuses were measured and they were chosed as the dependent variables, while the independent variable were the gestational age and biparietal diamete, as well as femur length. The regression analyses of the mean(M) and the standard deviation(SD) for each parameter were performed separately. Two observers randomly measured the brain fissures depth two hours apart to evaluate the interobserver repeatability.
Results:
The brain fissure depth in normal fetuses during geatational age between 18 to 38 weeks can be evaluated by Z-score model.Positive correlations were found between the depth of calacarine fissure, pariet-ooccipital fissure, sylvian fissure and gestational age, biparietal diameter and femur length.
Conclusions
Z-score can intuitively reflect the development of brain fissure more accurate, and is valuable, and can be used as a powerful supplement to the traditional method.
