Determination of lanthanum in whole blood by microwave digestion-inductively coupled plasma optical emission spectrometry / 药学实践杂志

Objective To evaluate the transdermal safety of lanthanum (La) in sunscreen and jellyfish sting protective lotion, establish a microwave digestion-inductively coupled plasma opticalemission spectroscopy (ICP-OES) method for determination of lanthanum (La) in rat’s whole blood. Methods The whole blood samples were digested by microwave and analyzed by inductively coupled plasma emission spectrometer (ICP-OES). Using 333.749 nm as the analysis line, the content of La in rat whole blood was determined. Results The correlation linearity of the standard curve of this method was good (r>0.9994), the detection limit of the method was 0.0025 μg/ml, the limit of quantification was 0.0077 μg/ml, the precision was less than 3%, and the recovery rate was between 94.9% and 102.0%. Conclusion The ICP-OES method based on microwave digestion is stable and reliable, and can provide an important basis for the study of the transdermal safety of lanthanum.

Tobacco use rate and associated factors in middle school students in China / 中华流行病学杂志

Objective To understand tobacco use rate and explore the factors associated with tobacco use in middle school students in China.Methods A self-administered questionnaire survey was conducted among 155 117 eligible middle students selected through multi-stage stratified cluster sampling from 31 provinces of China.The questionnaire consists of the following topics:tobacco use and cessation,passive smoking,access to tobacco products,tobacco control and tobacco advertisement,and knowledge about and attitudes to tobacco.Software SAS 9.3 was used for sample weighting and data analysis.Results Current tobacco use rate was 6.9％ in middle school students in China.The rate was higher in boys (11.2％) than in girls (2.2％),and in rural area (7.8％) than in urban area (4.8％).Students in western area had the highest tobacco use rate (10.3％),followed by the students in middle area (6.4％),and the rate in students in eastern area was lowest (4.5％).Parent smoking (especially mother smoking),friend smoking,teacher smoking,pocket money for a week ＞ 20 yuan,tobacco advertisement or promotion,passive smoking,misconception of tobacco addiction,active attitude to smoking behavior were the risk factors for tobacco use.Conclusions Smoking rate in boys in China was higher than the average global level.A comprehensive intervention strategy by Framework Convention on Tobacco Control should be used to reduce tobacco use in adolescents,including health education,increasing cigarette price,banning tobacco advertisement and promotion,and smoke-free legislation.

Effects of co-administration with morin and acetyl-resveratrolon pharmacokinetics of saquinavir in rats / 中国药理学通报

Aim To assess the impact of morin and acetyl-resveratrol on the oral bioavailability and pharmacokinetics of saquinavir (SQV), a substrate of P-glycoprotein (P-gp), in rats.Methods Twenty rats were randomized into four groups of equal size, including a control group, two intervention groups and a positive control group, and administered orally 30 mg·kg-1 SQV with or without 40 mg·kg-1 morin or acetyl-resveratrol or verapamil (as positive control).The plasma concentrations of saquinavir were determined using a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method, and the PK of SQV was assessed using non-compartmental analysis.Results The PK parameters values of SQV, SQV+morin, SQV+acetyl-resveratrol, SQV+verapamil were as follows: AUC0-t, 381.53 μg·h·L-1,185.53 μg·h·L-1, 360.43 μg·h·L-1, 529.95 μg·h·L-1;AUC0-∞, 409.48 μg·h·L-1, 228.52 μg·h·L-1,446.67 μg·h·L-1, 552.41 μg·h·L-1;Cmax, 110.80 μg·L-1, 86.44 μg·L-1, 139.84 μg·L-1, 423.60 μg·L-1;Tmax, 0.25 h, 0.25 h, 0.25 h, 0.50 h;T1/2, 5.72 h, 5.94 h, 6.78 h, 3.78 h;MRT0-∞, 10.30 h, 9.61 h, 12.30 h, 4.89 h;CL/F, 7.59 mL·kg-1·h-1, 13.88 mL·kg-1·h-1, 7.28 mL·kg-1·h-1, 5.52 mL·kg-1·h-1.Conclusions Multiple peak phenomenon can be observed in the plasma SQV profiles.Morin can significantly reduce the SQV oral bioavailability and affect SQV PK profiles while acetyl-resveratrol cannot significantly affect the SQV oral bioavailability and SQV PK profiles in rats.

Clinical Observation of Baizhu Shengjiang Decoction Combined with Prucalopride Succinate Tablets for Treatment of Chronic Functional Constipation / 广州中医药大学学报

Objective To observe the therapeutic effect of Baizhu Shengjiang Decoction combined with Prucalopride Succinate Tablets for chronic functional constipation. Methods Sixty patients with chronic functional constipation were randomly divided into treatment group and control group, 30 cases in each group. The treatment group was treated with Baizhu Shengjiang Decoction combined with Prucalopride Succinate Tablets orally, and the control group was treated with oral administration of Prucalopride Succinate Tablets alone. The therapeutic effects on traditional Chinese medicine (TCM) symptoms and constipation, and the follow-up therapeutic effect of the two groups were evaluated after treatment. During the three months after the completion of treatment course, the recurrence of constipation was monitored. Results (1) The cure rate of the treatment group was 90.0％ and that of the control group was 60.0％, indicating that the therapeutic effect on TCM symptoms in the treatment group was stronger than that of the control group(P < 0.05).(2) In respect of the relief of constipation, the markedly effective rate was 93.3％ in the treatment group and was 50.0％ in the control group, and the overall effective rate was 100.0％ in the treatment group and was 73.3％ in the control group, the difference being significant between the two groups(P<0.05 or P<0.01).(3) During the treatment, the percentage of patients with weekly completely spontaneous defecation frequency ≥3 was 86.7％ in the treatment group, and was 53.3％ in the control group, the difference being significant (P < 0.05). (4) The results of 3-month follow-up after the completion of treatment course showed that one case from the treatment group had the recurrence of constipation, and the recurred cases from the control group were 6, the difference being significant (P < 0.05). Conclusion Oral use of Baizhu Shengjiang Decoction combined with Prucalopride Succinate Tablets exerts certain therapeutic effect for chronic functional constipation, which is effective both on relieving constipation symptoms and on reducing recurrence rate.

Effect and safety of Endoscopic retrograde appendicitis therapy in treating patients with uncomplicated acute appendicitis / 中国内镜杂志

Objective To study the effect and safety of endoscopic retrograde appendicitis therapy (ERAT) in treating patients with uncomplicated acute appendicitis. Methods Patients with uncomplicated acute appendicitis were enrolled and divided into ERAT group and LA group received laparoscopic appendectomy. Then compare treat-ment condition, complications and follow-up of the two groups. Results ERAT were completed successfully in all the patients in ERAT group, while one patient underwent a reversion to open appendectomy for technical difficulties in LA group. Mean operative time was (49.7 ± 18.2) min for ERAT group and (68.9 ± 25.9) min for LA group (P <0.05). Fever relief time (1.3 ± 0.5) d, WBC normalization time (2.0 ± 0.9) d, mean bed time (0.1 ± 0.2) d and mean hospital stay (3.3 ± 1.6) d for ERAT group were significantly lower than LA group (P <0.05). 14 patients with intra-luminal appendicoliths (7 of massive appendicoliths, 4 of broken appendicoliths and 3 of broken appendicoliths with luminal stenosis) underwent endoscopic lithotomy successfully in ERAT group, resulting in a success rate of 100.00%. One patient presented perforation after ERAT was cured with conservative treatment. During the follow-up of at least 1/2 year, the rate of recurrence was 10.00% in ERAT group. 1 patient (5.00%) underwent LA at the 5th month after ERAT during the follow-up. Conclusion ERAT is an effective and safe therapy in treating patients with uncomplicated acute appendicitis with advantages of minimal invasiveness and quick recovery. Uncomplicated acute appendicitis with appendicoliths and/or luminal stenosis are the most suitable indications for ERAT.
